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...

UBUNTU-CVE-2026-89513

In the Linux kernel, the following vulnerability has been resolved: RISC-V: KVM: Fix PMU event info array size overflow SBI PMU EVENTGETINFO stores guest-controlled numevents sizeofeinfo in a 32-bit integer. On RV64, numevents = 0x10000001 makes 0x100000010 truncate to 16. KVM then allocates one...

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 ...
