Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: xfs: fix undersized l_iclog_roundoff
 values If the superblock doesn't list a log stripe unit, we set the incore log roundoff value to 512. This
 leads to corrupt logs and unmountable filesystems in generic/617 on a disk with 4k physical sectors... XFS
 (sda1): Mounting V5 Filesystem ff3121ca-26e6-4b77-b742-aaff9a449e1c XFS (sda1): Torn write (CRC failure)
 detected at log block 0x318e. Truncating head block from 0x3197. XFS (sda1): failed to locate log tail XFS
 (sda1): log mount/recovery failed: error -74 XFS (sda1): log mount failed XFS (sda1): Mounting V5
 Filesystem ff3121ca-26e6-4b77-b742-aaff9a449e1c XFS (sda1): Ending clean mount ...on the current xfsprogs
 for-next which has a broken mkfs. xfs_info shows this... meta-data=/dev/sda1 isize=512 agcount=4,
 agsize=644992 blks = sectsz=4096 attr=2, projid32bit=1 = crc=1 finobt=1, sparse=1, rmapbt=1 = reflink=1
 bigtime=1 inobtcount=1 nrext64=1 = exchange=1 metadir=1 data = bsize=4096 blocks=2579968, imaxpct=25 =
 sunit=0 swidth=0 blks naming =version 2 bsize=4096 ascii-ci=0, ftype=1, parent=1 log =internal log
 bsize=4096 blocks=16384, version=2 = sectsz=4096 sunit=0 blks, lazy-count=1 realtime =none extsz=4096
 blocks=0, rtextents=0 = rgcount=0 rgsize=268435456 extents = zoned=0 start=0 reserved=0 ...observe that
 the log section has sectsz=4096 sunit=0, which means that the roundoff factor is 512, not 4096 as you'd
 expect. We should fix mkfs not to generate broken filesystems, but anyone can fuzz the ondisk superblock
 so we should be more cautious. I think the inadequate logic predates commit a6a65fef5ef8d0, but that's
 clearly going to require a different backport. (CVE-2026-43365)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.395.4 or later.
