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 jfs_truncate_nolock()

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:

block_write_begin() { jfs_write_failed() { jfs_truncate() { jfs_truncate_nolock() { txEnd() { ... log = JFS_SBI(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 ndisc_send_skb()

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

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

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

openvswitch: use RCU protection in ovs_vport_cmd_fill_info()

ovs_vport_cmd_fill_info() can be called without RTNL or RCU.

Use RCU protection and dev_net_rcu() 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 __neigh_notify()

__neigh_notify() 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 ndisc_alloc_skb()

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

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