| In the Linux kernel, the following vulnerability has been resolved:
gpio: mvebu: free generic chips on unbind
irq_alloc_domain_generic_chips() allocates generic chip data that must
be freed via irq_domain_remove_generic_chips(). The devres action
mvebu_gpio_remove_irq_domain() only called irq_domain_remove(), which
only frees the generic chips if IRQ_DOMAIN_FLAG_DESTROY_GC is set.
Call irq_domain_remove_generic_chips() explicitly before
irq_domain_remove() instead. |
| In the Linux kernel, the following vulnerability has been resolved:
fbdev: radeon: fix potential memory leak in radeonfb_pci_register()
The function radeonfb_pci_register() allocates memory for modelist
(by calling radeon_check_modes() which calls fb_add_videomode()).
The memory is appended to info->modelist, but is not freed in subsequent
error paths. Fix this by calling fb_destroy_modelist(). |
| In the Linux kernel, the following vulnerability has been resolved:
fbdev: broadsheetfb: fix potential memory leak in broadsheetfb_probe()
The memory allocated for pagerefs in fb_deferred_io_init() is not freed
on the error path. Fix it by calling fb_deferred_io_cleanup(). |
| In the Linux kernel, the following vulnerability has been resolved:
fbdev: metronomefb: fix potential memory leak in metronomefb_probe()
The memory allocated for pagerefs in fb_deferred_io_init() is not freed
on the error path. Fix it by calling fb_deferred_io_cleanup(). |
| In the Linux kernel, the following vulnerability has been resolved:
drm/xe: free madvise VMA array on L2 flush failure
xe_vm_madvise_ioctl() allocates madvise_range.vmas in get_vmas().
After get_vmas() succeeds with at least one VMA, error paths must go
through free_vmas so the array is released before the madvise details are
destroyed.
The L2 flush validation path added for PAT madvise rejects some
SVM/userptr ranges after get_vmas() has succeeded, but jumps directly to
madv_fini. This skips kfree(madvise_range.vmas), leaking the VMA array on
each failed ioctl.
Jump to free_vmas instead, matching the other validation failure paths
after get_vmas() has succeeded.

| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: L2CAP: fix tx ident leak for commands without a response
Commit 6c3ea155e5ee ("Bluetooth: L2CAP: Fix not tracking outstanding
TX ident") changed ident allocation to use an IDA, releasing idents in
l2cap_put_ident() when the matching response command is received.
But identifiers allocated for commands that have no response defined
are never released. In particular L2CAP_LE_CREDITS is sent repeatedly for
the lifetime of an LE CoC channel, so a peer streaming data to the
host exhausts the 1-255 ident range after 254 credit packets. From
then on l2cap_get_ident() fails:
kernel: Bluetooth: Unable to allocate ident: -28
and every subsequent L2CAP_LE_CREDITS packet is sent with ident 0,
which is invalid (Core Spec, Vol 3, Part A, Section 4: "Signaling
identifier 0x00 is an invalid identifier and shall never be used in
any command"). Remote stacks that validate the ident drop these
commands, never receive new credits, and the channel stalls
permanently. With default socket buffers this happens after roughly 0.5 MB
of received data (the exact amount depends on the socket receive buffer):
< ACL Data TX: Handle 2048 flags 0x00 dlen 12
LE L2CAP: LE Flow Control Credit (0x16) ident 0 len 4
Source CID: 64
Credits: 1
Release the ident immediately after sending L2CAP_LE_CREDITS since no
response will ever release it. Use a local variable instead of
chan->ident so that an ident that an EXT_FLOWCTL channel may be waiting on
(e.g. a pending reconfigure) is not overwritten by a credit packet.
Also add the missing L2CAP_LE_CONN_RSP case to l2cap_put_ident() so
idents allocated for outgoing L2CAP_LE_CONN_REQ commands are released
when the response arrives. |
| In the Linux kernel, the following vulnerability has been resolved:
netfs: Fix writeback error handling
Fix the error handling in writeback_iter() loop. If an error occurs,
writeback_iter() needs to be called again with *error set to the error so
that it can clean up iteration state. Further, the current folio needs
unlocking and redirtying. |
| In the Linux kernel, the following vulnerability has been resolved:
net: phy: sfp: free mii_bus in sfp_i2c_mdiobus_destroy
sfp_i2c_mdiobus_create() allocates the I2C MDIO bus with mdio_i2c_alloc(),
a plain (non-devm) allocation, and registers it. sfp_i2c_mdiobus_destroy()
only unregisters the bus and clears sfp->i2c_mii without calling
mdiobus_free(). As the only reference to the bus is then cleared, the
struct mii_bus is leaked.
This is hit whenever a copper/RollBall SFP module that instantiated an MDIO
bus is removed: sfp_sm_main() takes the global teardown path and calls
sfp_i2c_mdiobus_destroy(). sfp_cleanup(), on driver unbind, frees
sfp->i2c_mii directly, which is why the leak only triggered on module
hot-removal and not on unbind.
Free the bus in sfp_i2c_mdiobus_destroy() to match the allocation done in
sfp_i2c_mdiobus_create(). |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix insn_aux_data leak on verifier err_free_env path
When bpf_check() allocates env->insn_aux_data successfully but later
fails to allocate env->succ, it jumps directly to err_free_env.
The existing vfree(env->insn_aux_data) sits before the err_free_env
label, so that direct jump bypasses it and leaks insn_aux_data.
Move vfree(env->insn_aux_data) into err_free_env so all early and late
exit paths release it consistently. |
| In the Linux kernel, the following vulnerability has been resolved:
octeontx2-pf: Fix leak of SQ timestamp buffer on teardown
The send-queue timestamp ring is allocated with qmem_alloc() when
timestamping is used, but otx2_free_sq_res() never freed sq->timestamps,
leaking that memory across ifdown and device removal. Add the missing
qmem_free() alongside the other SQ companion buffers. |
| In the Linux kernel, the following vulnerability has been resolved:
apparmor: aa_label_alloc use aa_label_free on alloc failure
aa_label_alloc() allocates a secid before allocating or taking the label
proxy. If the later proxy step fails, the error path only freed the label
memory, leaking any resources initialized by aa_label_init().
Use aa_label_free() on the failure path so partially initialized labels
release their secid and other label resources before the backing memory is
freed. |
| In the Linux kernel, the following vulnerability has been resolved:
sctp: fix err_chunk memory leaks in INIT handling
When sctp_verify_init() encounters unrecognized parameters, it allocates an
err_chunk to report them. However, this chunk is leaked in several code
paths:
1. In sctp_sf_do_5_1B_init(), if security_sctp_assoc_request() fails after
sctp_verify_init() has populated err_chunk, the function returns
immediately without freeing it.
2. In sctp_sf_do_unexpected_init(), the same leak occurs on the
security_sctp_assoc_request() failure path.
3. In sctp_sf_do_unexpected_init(), on the success path after copying
unrecognized parameters to the INIT-ACK, the function returns without
freeing err_chunk, unlike sctp_sf_do_5_1B_init() which properly frees
it.
Fix all three leaks by adding sctp_chunk_free(err_chunk) calls before
returning in the error paths and on the success path in
sctp_sf_do_unexpected_init(). |
| In the Linux kernel, the following vulnerability has been resolved:
tipc: reject inverted service ranges from peer bindings
tipc_update_nametbl() inserts a binding advertised by a peer node using
the lower and upper service-range bounds taken directly from the wire,
without checking that lower <= upper. The local bind path validates the
ordering (tipc_uaddr_valid()), but the name-distribution path does not.
A binding with lower > upper is inserted at the far end of the
service-range rbtree (keyed on lower) where no lookup or withdrawal can
ever match it (service_range_foreach_match() requires sr->lower <= end).
The publication, its service_range node and the augmented rbtree entry
are then leaked for the lifetime of the namespace, and there is no
per-peer cap equivalent to TIPC_MAX_PUBL on locally created bindings.
Reject inverted ranges in the network path as well. A peer node can
otherwise leak unbounded binding-table memory by sending PUBLICATION
items with lower > upper. |

crypto: cavium/cpt - fix DMA cleanup using wrong loop index
The sg_cleanup error path used list[i] instead of list[j] when unmapping
DMA buffers, leaking successfully mapped entries and repeatedly unmapping
the failed one. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/core: Fix FRMR aging push to queue error flow
Aging pools with pinned handles requires moving handles from the
active queue to a non-empty inactive queue that might fail on new page
allocation, we are currently not handling the fault and leaking any mkey
that fails the push.
Fix by Introducing push_queue_to_queue_locked() that fills the
destination's partial tail page from the source and then splices the
remaining source pages onto the destination, performing no allocation.
Replace the per-handle move loop in age_pinned_pool() and the
open-coded splice in pool_aging_work() with calls to the helper.
As the helper cannot fail under memory pressure, removing a class of
GFP_ATOMIC allocations under the pool lock and simplifying the error
flow. |
| In the Linux kernel, the following vulnerability has been resolved:
NFSD: Handle layout stid in nfsd4_drop_revoked_stid()
nfsd4_drop_revoked_stid() has no SC_TYPE_LAYOUT case, so when a
client sends FREE_STATEID for an admin-revoked layout stid, the
default branch releases cl_lock and returns without unhashing or
releasing the stid. The stid remains in the IDR and on the
per-client list until the client is destroyed.
Remove the layout stid from the per-client list and call
nfs4_put_stid() to drop the creation reference. When the
refcount reaches zero, nfsd4_free_layout_stateid() handles the
remaining cleanup: cancelling the fence worker, removing from
the per-file list, and freeing the slab object. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7921: fix resource leak in probe error path
When pcim_iomap_region() or devm_kmemdup() fail, the code returns
directly without cleaning up previously allocated resources:
- mt76_device allocated by mt76_alloc_device()
- pci irq vectors allocated by pci_alloc_irq_vectors()
Fix this by jumping to the existing error cleanup path instead of
returning directly. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: fix memory leak in ath12k_wifi7_dp_rx_h_verify_tkip_mic()
In ath12k_wifi7_dp_rx_h_verify_tkip_mic(), the call to
ath12k_dp_rx_check_nwifi_hdr_len_valid() may return false when the
NWIFI header length is invalid, causing the function to abort early with
-EINVAL.
When this happens, the error propagates to
ath12k_wifi7_dp_rx_h_defrag(), which clears first_frag by setting it
to NULL. As a result, the corresponding MSDU is no longer referenced
by the defragmentation path and is never freed.
This leads to a memory leak for the affected MSDU on this error path.
Proper cleanup is required to ensure the MSDU is released when header
validation fails during TKIP MIC verification.
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.1.c5-00302-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.115823.3 |
| In the Linux kernel, the following vulnerability has been resolved:
md/raid10: reset read_slot when reusing r10bio for discard
put_all_bios() always drops devs[i].bio, but it only drops
devs[i].repl_bio when r10_bio->read_slot < 0. If discard reuses an
r10bio that was previously used for a read, read_slot can still be
non-negative, and discard cleanup can skip bio_put() on repl_bio.
Reset read_slot to -1 when preparing an r10bio for discard so the
replacement bio is always released correctly. |
| In the Linux kernel, the following vulnerability has been resolved:
accel/amdxdna: Fix leak when pinning ubuf pages
When pin_user_pages_fast() returns fewer pages than requested, the pages
that were successfully pinned are not released, leading to a leak.
Fix this by unpinning any partially pinned pages before returning failure. |
