Summary
kernel security update
Details

The Linux Kernel, the operating system core itself.

Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

jfs: add check read-only before truncation in jfstruncatenolock()

Added a check for "read-only" mode in the jfs_truncate_nolock function to avoid errors related to writing to a read-only filesystem.

Call stack:

blockwritebegin() { jfswritefailed() { jfstruncate() { jfstruncatenolock() { txEnd() { ... log = JFSSBI(tblk->sb)->log; // (log == NULL)

If the isReadOnly(ip) condition is triggered in jfs_truncate_nolock, the function execution will stop, and no further data modification will occur. Instead, the xtTruncate function will be called with the "COMMIT_WMAP" flag, preventing modifications in "read-only" mode.(CVE-2024-58094)

In the Linux kernel, the following vulnerability has been resolved:

ndisc: extend RCU protection in ndiscsendskb()

ndiscsendskb() can be called without RTNL or RCU held.

Acquire rcureadlock() earlier, so that we can use devnetrcu() and avoid a potential UAF.(CVE-2025-21760)

In the Linux kernel, the following vulnerability has been resolved:

openvswitch: use RCU protection in ovsvportcmdfillinfo()

ovsvportcmdfillinfo() can be called without RTNL or RCU.

Use RCU protection and devnetrcu() to avoid potential UAF.(CVE-2025-21761)

In the Linux kernel, the following vulnerability has been resolved:

arp: use RCU protection in arp_xmit()

arp_xmit() can be called without RTNL or RCU protection.

Use RCU protection to avoid potential UAF.(CVE-2025-21762)

In the Linux kernel, the following vulnerability has been resolved:

neighbour: use RCU protection in _neighnotify()

_neighnotify() can be called without RTNL or RCU protection.

Use RCU protection to avoid potential UAF.(CVE-2025-21763)

In the Linux kernel, the following vulnerability has been resolved:

ndisc: use RCU protection in ndiscallocskb()

ndiscallocskb() can be called without RTNL or RCU being held.

Add RCU protection to avoid possible UAF.(CVE-2025-21764)
