CVE-2026-46086

The CVE-2026-46086 issue affects the Linux kernel’s bridge FDB code. Local FDB entries could be rewritten in place by fdb_delete_local(), changing f->dst to another port or NULL while entries remain alive. Several bridge RCU readers (e.g., br_fdb_fillbuf() via brforward_read()) may observe f-&...

CVE-2026-45994

The CVE-2026-45994 issue affects the Linux kernel ibmasm: command_file_write, where a kernel buffer is allocated with count bytes and user data copied without validating against the dot command header, enabling out-of-bounds reads via get_dot_command_size/timeout and memcpy_toio. Patches introduc...

CVE-2026-45994

In the Linux kernel, the following vulnerability has been resolved: ibmasm: fix OOB reads in commandfilewrite due to missing size checks The commandfilewrite handler allocates a kernel buffer of exactly count bytes and copies user data into it, but does not validate the buffer against the dot...

CVE-2026-45991

The CVE-2026-45991 entry concerns the Linux kernel UDF filesystem. The root cause is in handle_partition_descriptor() where partition descriptors are deduplicated by partition number, but appended slots do not record partnum, allowing repeated Partition Descriptors to accumulate and grow num_part...

CVE-2026-1933

A flaw was found in Samba’s handling of NTFS-style reparse points on shares configured with read only = yes. Due to missing SMB-layer access checks, authenticated users with underlying filesystem write permissions may create or delete reparse point metadata through SMB operations even on read-onl...

CVE-2026-45984

In the Linux kernel, the following vulnerability has been resolved: gfs2: Fix use-after-free in iomap inline data write path The inline data buffer head dibh is being released prematurely in gfs2iomapbegin via releasemetapath while iomap-inlinedata still points to dibh-bdata. This causes a...

CVE-2026-45984

The CVE-2026-45984 issue is a concrete Linux-kernel vulnerability in the GFS2 iomap inline data write path. A data buffer head (dibh) is released prematurely via release_metapath() in gfs2_iomap_begin(), while iomap->inline_data still references dibh->b_data, causing a use-after-free when i...

CVE-2026-45961

CVE-2026-45961 in the Linux kernel’s GFS2 filesystem is fixed: memory leaks occur on gfs2_fill_super() error paths when transitioning to read-write mode. Two leaks are addressed: (1) kernel thread objects (logd, quotad) not destroyed after init_threads() if failure occurs; (2) a quota bitmap buff...
