| In the Linux kernel, the following vulnerability has been resolved:
dm-pcache: clamp the tail kset read to the segment data region
The tail-kset read in cache_replay(), the writeback worker and the GC
worker bounds its length by PCACHE_SEG_SIZE - seg_off, the raw segment
size rather than the data region. A tail near the segment end reads past
the segment data into the following control area.
Clamp the read to cache_seg_remain(), the data region. |

| In the Linux kernel, the following vulnerability has been resolved:
HID: corsair-void: Check size of status and firmware events before reading them
Malformed status and firmware events could cause an out-of-bounds read since
the size wasn't being checked. Check the size and warn on unexpected values to
avoid this. |
| 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:
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. |
