Linux Distros Unpatched Vulnerability : CVE-2026-89656

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - libceph: reject buckets with mismatched CRUSH ids crushdecode stores bucket data by array slot, and the mapper later derives the per-bucket workspace index from...

CVE-2026-89725

A flaw was found in the Linux kernel's media: cec: stm32 driver. A remote attacker can exploit an out-of-bounds write vulnerability by sending an overlong Consumer Electronics Control CEC message without an end-of-message signal. This causes the driver to write beyond an allocated buffer,...

CVE-2026-89656

In the Linux kernel, the following vulnerability has been resolved: libceph: reject buckets with mismatched CRUSH ids crushdecode stores bucket data by array slot, and the mapper later derives the per-bucket workspace index from the decoded bucket id. A malformed map can therefore make one bucket...

DEBIAN-CVE-2026-89611

In the Linux kernel, the following vulnerability has been resolved: ntfs: validate non-resident attribute offsets ntfsattrupdatemeta shifts the attribute name when converting between non-sparse and sparse attributes. Converting to sparse also adds the compressedsize field before the name and...

AZL-100100 CVE-2026-89495 affecting package kernel 6.6.150.1-1

In the Linux kernel, the following vulnerability has been resolved: ocfs2: bound namelen in dlmmigraterequesthandler Patch series "ocfs2/dlm: bound peer-controlled lengths in the o2dlm". The o2dlm receive handlers trust u8 length and count fields from the wire without bounding them, so a node in ...

DEBIAN-CVE-2026-80960

In the Linux kernel, the following vulnerability has been resolved: dm-pcache: validate on-media segnum against the cache device size segnum is read from the crc32c-only superblock, so whoever supplies the cache device on a table load CAPSYSADMIN controls it. It sizes cache-segments and is the...

CVE-2026-89702 nfsd: size fh_verify server sockaddr slot by xpt_locallen

In the Linux kernel, the following vulnerability has been resolved: nfsd: size fhverify server sockaddr slot by xptlocallen The nfsdfhverify and nfsdfhverifyerr tracepoints declare the server sockaddr slot sized by xptremotelen but fill it from xptlocal using xptlocallen: TPSTRUCTentry...

CVE-2026-89656

CVE-2026-89656 is an out-of-bounds write in the libceph subsystem of the Linux kernel . The crush_decode() function stores bucket data by array slot, but a malformed CRUSH map can cause one bucket to alias another's workspace by encoding a mismatched id. When a larger source bucket's permutation ...

CVE-2026-89656 libceph: reject buckets with mismatched CRUSH ids

In the Linux kernel, the following vulnerability has been resolved: libceph: reject buckets with mismatched CRUSH ids crushdecode stores bucket data by array slot, and the mapper later derives the per-bucket workspace index from the decoded bucket id. A malformed map can therefore make one bucket...

CVE-2026-89495

CVE-2026-89495 affects the OCFS2/DLM (o2dlm) subsystem in the Linux kernel . The migration and recovery message handlers trust peer-supplied u8 length fields (namelen, lockname_len, num_locks) without bounding them before passing them to memcpy, resulting in a heap out-of-bounds write of up to ~2...

EUVD-2026-76400

In the Linux kernel, the following vulnerability has been resolved: ocfs2: validate lengths in dlmmiglockreshandler A node receiving a DLMMIGLOCKRES message trusts several fields of the peer-supplied dlmmigratablelockres without validation. numlocks and locknamelen are bounded only on the sending...

CVE-2026-89471 power: supply: cros_usbpd-charger: bound the EC-reported port count

In the Linux kernel, the following vulnerability has been resolved: power: supply: crosusbpd-charger: bound the EC-reported port count crosusbpdchargerprobe reads two port counts from the EC and uses one of them, numchargerports, as the loop bound when populating a fixed-size array: struct portda...

CVE-2026-81000 net: tun: bound receive headroom

In the Linux kernel, the following vulnerability has been resolved: net: tun: bound receive headroom tungetuser uses tun-align both as skb headroom and when choosing how much packet data to keep linear. OVS can propagate an oversized headroom request from another port to TUN or TAP. When align is...
