CVE-2026-89725

CVE-2026-89725 affects the Linux kernel's STM32 CEC platform driver (media/cec/stm32). The root cause is an out-of-bounds write in stm32_rx_done(), which appends each received CEC byte to a fixed 16-byte buffer (CEC_MAX_MSG_SIZE) using rx_msg.len as an unchecked write index. Because the number of...

CVE-2026-89724

This vulnerability affects the Linux kernel's media vicodec FWHT encoder . The root cause is an out-of-bounds write : vidioc_s_fmt_vid_out() sizes the CAPTURE buffer using pixfmt_fwht.sizeimage_mult of 3, but for 4-component pixel formats the unencoded fallback path in encode_plane() writes all f...

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-2026-89702 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-2026-89702

CVE-2026-89702 is a Linux kernel vulnerability in the nfsd_fh_verify and nfsd_fh_verify_err tracepoints. These tracepoints declare the server sockaddr slot sized by xpt_remotelen but populate it using xpt_locallen . When xpt_locallen exceeds xpt_remotelen, __assign_sockaddr's memcpy writes past t...

EUVD-2026-76586

In the Linux kernel, the following vulnerability has been resolved: nfsd: fix XDR length calculation in nfsd4ffencodelayoutget The XDR buffer size calculation in nfsd4ffencodelayoutget has multiple errors that can result in either an out-of-bounds write or leaking uninitialized kernel memory to t...

CVE-2026-89674 nfsd: fix XDR length calculation in nfsd4_ff_encode_layoutget

In the Linux kernel, the following vulnerability has been resolved: nfsd: fix XDR length calculation in nfsd4ffencodelayoutget The XDR buffer size calculation in nfsd4ffencodelayoutget has multiple errors that can result in either an out-of-bounds write or leaking uninitialized kernel memory to t...

CVE-2026-89674

CVE-2026-89674 is a vulnerability in the Linux kernel 's NFS server daemon (nfsd), specifically in the nfsd4_ff_encode_layoutget() function. The XDR buffer size calculation contains multiple errors: the file handle length fails to account for XDR padding, the uid/gid lengths use an incorrect form...

EUVD-2026-76568

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...

In the Linux kernel, the following vulnerability has been resolved: ceph: reject exporttargets ranks = CEPHMAXMDS in mdsmap decode MDSMap exporttargets entries are monitor controlled. checknewmap uses each entry as a bit number in a fixed stack bitmap, so a rank outside the protocol namespace can...

CVE-2026-89653 ceph: reject export_targets ranks >= CEPH_MAX_MDS in mdsmap decode

In the Linux kernel, the following vulnerability has been resolved: ceph: reject exporttargets ranks = CEPHMAXMDS in mdsmap decode MDSMap exporttargets entries are monitor controlled. checknewmap uses each entry as a bit number in a fixed stack bitmap, so a rank outside the protocol namespace can...

CVE-2026-89653

This vulnerability affects the Linux kernel's Ceph filesystem (ceph) MDSMap decode path . The check_new_map() function uses monitor-controlled export_targets entries as bit numbers in a fixed stack bitmap. A rank value at or above CEPH_MAX_MDS causes set_bit() to write past the end of the array, ...

In the Linux kernel, the following vulnerability has been resolved: ceph: bound copied dentry name length in NFS export getname cephgetname copies the MDS-supplied name into the caller's NAMEMAX-sized buffer with memcpyname, rinfo-dname, rinfo-dnamelen and then writes namerinfo-dnamelen = 0,...

CVE-2026-89652

CVE-2026-89652 is a slab out-of-bounds write in the Linux kernel's Ceph filesystem NFS export path. The functions ceph_get_name() and __get_snap_name() copy MDS-supplied dentry names into a NAME_MAX-sized buffer via memcpy without validating the length against NAME_MAX. A malicious or compromised...
