| In the Linux kernel, the following vulnerability has been resolved:
zram: validate deflate params
We must validate user-supplied deflate winbits before we pass it to
zlib_deflate_workspacesize(), which triggers BUG_ON() if winbits value is
outside of valid ranges. |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: GICv2: Don't WARN on out-of-range GICV_DIR INTID
vgic_v2_deactivate() passes the INTID a guest wrote to GICV_DIR straight
to vgic_get_vcpu_irq(), and treats a failed lookup as a "can't happen"
condition with WARN_ON_ONCE().
The guest can make it happen at will, though: for any INTID outside of
the implemented SGI, PPI and SPI ranges the lookup returns NULL, since
GICv2 has no LPIs. A guest running with EOImode==1 writing such an INTID
to GICV_DIR triggers the WARN, and panics hosts running with
panic_on_warn.
Drop the WARN and ignore failed lookups. |
| In the Linux kernel, the following vulnerability has been resolved:
module: validate string table section types
In elf_validity_cache_sechdrs, section sizes and offsets are validated,
unless the section type is SHT_NULL or SHT_NOBITS.
Later, elf_validity_cache_secstrings and elf_validity_cache_index_str
access the section name table (.shstrtab) and symbol string table
(.strtab) headers without first ensuring that their types are
SHT_STRTAB. If a section type is SHT_NULL or SHT_NOBITS, sh_offset has
not been validated and may reference out-of-bounds memory when
dereferenced in elf_validity_cache_secstrings or
elf_validity_cache_strtab.
Validate that both string section headers are of type SHT_STRTAB before
caching them. |

| In the Linux kernel, the following vulnerability has been resolved:
NFS/localio: fix ref leak on nfs_uuid_add_file failure
When nfs_uuid_add_file() races with nfs_uuid_put() tearing down
uuid->net, it returns -ENXIO without publishing nfl->nfs_uuid via
rcu_assign_pointer(). nfs_open_local_fh() then enters its error
branch and only releases the slot's file ref and its paired net
ref plus its own entry-time net ref, while the close path is a
no-op:
nfs_close_local_fh()
nfs_uuid = rcu_dereference(nfl->nfs_uuid);
if (!nfs_uuid) { rcu_read_unlock(); return; } /* always */
nfsd_open_local_fh() returns localio holding a caller-owned +1
nfsd_file reference (from nfsd_file_get() after
nfsd_file_acquire_local()) and an entry-time nfsd_net reference
(from its first nfsd_net_try_get()) embedded as nf->nf_net. Both
are leaked on the failure path, pinning one nfsd_file (and the
underlying struct file, dentry, inode) and one nfsd_net_ref per
occurrence, which blocks nfsd_net and netns teardown.
Fix by releasing the caller-owned file ref and its net ref through
the existing helper, using a stack-local RCU pointer so the helper
can xchg it out, then returning -ENXIO so callers do not
dereference a localio whose slot has been cleared:
struct nfsd_file __rcu *tmp = RCU_INITIALIZER(localio);
nfs_to_nfsd_file_put_local(pnf);
nfs_to_nfsd_file_put_local(&tmp);
localio = ERR_PTR(-ENXIO);
The trailing nfs_to_nfsd_net_put(net) continues to release the
outer net ref, so all three nfsd_net_try_get() increments are
balanced on the error branch. |

| In the Linux kernel, the following vulnerability has been resolved:
iomap: don't free integrity payload that doesn't exist
fs_bio_integrity_alloc might not allocate a bio integrity payload if PI
verification is disabled on the block device. Check for that case before
calling fs_bio_integrity_free in iomap_bio_read_folio_range_sync to
avoid a NULL pointer dereferences.
Make the branch cover the PI verification as well - while
fs_bio_integrity_verify works without an integrity payload, it requires
one to actually do useful work. |
| In the Linux kernel, the following vulnerability has been resolved:
i3c: renesas: Fix out-of-bounds access for newdevs mask
When software initiates DAA (Dynamic Address Assignment), the controller
reports the result via the NRSPQP (Normal Response Queue Port Register).
The data length field of the response descriptor, which is accessible
through the NRSPQP register, indicates the number of devices remaining
after DAA. Consequently, when the bus is empty, this field contains the
maximum number of devices supported by the controller (8 for the Renesas
I3C controller).
Adjust the condition that computes the newly discovered devices bitmask
to prevent an out-of-bounds when the I3C bus is empty. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: uvc: Fix null pointer dereference in uvcg_video_init()
In uvcg_video_init(), if kthread_run_worker() fails,
the error logged uses uvcg_err(), however, the pointer it uses:
video->uvc is not assigned at this point, triggering a null
pointer dereference. Fix this by directly using uvc->func which
is assigned already. |

| In the Linux kernel, the following vulnerability has been resolved:
nvmet-tcp: Do not WARN on remotely-controlled oversized SGL allocations
When fuzzing the nvme target code, I tripped a kernel warning in
nvmet_tcp_map_data() because the length passed into the allocator is
controlled by the remote initiator.
A remote initiator that sends a command with an SGL claiming a huge
number, can create a scatterlist and iovec allocation of over 1 million
entries, which causes the backing kmalloc call to exceed MAX_PAGE_ORDER
and then the page allocator will trip on a WARN_ON_ONCE_GFP() message:
WARNING: mm/page_alloc.c:5280 __alloc_frozen_pages_noprof
Workqueue: nvmet_tcp_wq nvmet_tcp_io_work
...
sgl_alloc_order
nvmet_tcp_map_data
nvmet_tcp_try_recv_pdu
As it's never good to trip a kernel warning remotely due to many systems
having panic-on-warn enabled, let's silence it by just add GFP_NOWARN to
the allocation flags. |

| The cupsUTF32ToUTF8() function in CUPS's cups/transcode.c lacks a source-length bound and can read past the end of the source buffer, resulting in a heap out-of-bounds read. This is reachable via SNMP supply-description parsing in backend/snmp-supplies.c with attacker-controlled content. |
| In multiple functions of SmsController.java, there is a possible escalation of privilege due to a missing permission check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. |
| Axolotl before 0.19.0 contains a remote code execution vulnerability in the multipack patch path where trust_remote_code defaults to None instead of False, causing the security guard to be bypassed. Attackers can execute arbitrary Python code by crafting a malicious Hugging Face model repository selected as base_model, which is loaded with hardcoded trust_remote_code=True during AutoModelForCausalLM.from_pretrained. |
