CVE-2026-97598

The Linux kernel contains a vulnerability in the ipv4: fib component where the fib_empty_table() function probes every table ID starting from 1 until a free one is found. In a dense set of IDs, this causes each probe to walk a growing hash chain while the RTNL is held. To mitigate this, the autom...

CVE-2026-97598 ipv4: fib: bound automatic table ID allocation

In the Linux kernel, the following vulnerability has been resolved: ipv4: fib: bound automatic table ID allocation fibemptytable probes every table ID from 1 until it finds a free one. IPv4 tables are stored in a 256-bucket hash table, so a dense set of IDs makes each probe walk a growing hash...

In the Linux kernel, the following vulnerability has been resolved: s390/crypto: Map EBUSY to EIO when key conversion fails repeatedly When hardware persistently returns -EBUSY after exhausting retries, the error propagates to cryptofinalizerequest. The crypto API's completion wrapper treats -EBU...

CVE-2026-97588

The Linux kernel contains a vulnerability in the s390/crypto component where persistent -EBUSY errors from hardware during key conversion result in the error being swallowed by the crypto API's completion wrapper. Because the wrapper treats -EBUSY as a queueing status, the completion callback fai...

CVE-2026-97584

The Linux kernel contains a vulnerability in the afs component related to an incorrect memory free operation in the afs_lookup_server() function. Specifically, the function was incorrectly freeing an existing server's endpoint state during the cleanup of a candidate server, even though the candid...

In the Linux kernel, the following vulnerability has been resolved: smb: client: avoid leaking refcount in cifsqueueoplockbreak cifsqueueoplockbreak unconditionally takes a reference on the target file before queueing cifsoplockbreak. Only that work item decreases the reference counter again. If...

CVE-2026-97556

The Linux kernel contains a vulnerability in the SMB client where a reference count leak occurs when cifs_sb_tlink() fails, specifically in setups using the "-o multiuser" option. The cifs_oplock_break() function fails to release the file reference in this specific failure path, which can lead to...
