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

apparmor: Fix double free of ns_name in aa_replace_profiles()

if ns_name is NULL after 1071 error = aa_unpack(udata, &lh, &ns_name);

and if ent->ns_name contains an ns_name in 1089 } else if (ent->ns_name) {

then ns_name is assigned the ent->ns_name 1095 ns_name = ent->ns_name;

however ent->ns_name is freed at 1262 aa_load_ent_free(ent);

and then again when freeing ns_name at 1270 kfree(ns_name);

Fix this by NULLing out ent->ns_name after it is transferred to ns_name

The Linux Kernel, the operating system core itself. Security Fix(es):

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

f2fs: fix to detect potential corrupted nid in free_nid_list

As reported, on-disk footer.ino and footer.nid is the same and out-of-range, let's add sanity check on f2fs_alloc_nid() to detect any potential corruption in free_nid_list.(CVE-2025-68315)

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

ntfs3: Fix uninit buffer allocated by __getname()

Fix uninit errors caused after buffer allocation given to 'de'; by initializing the buffer with zeroes. The fix was found by using KMSAN.(CVE-2025-68727)

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

netfilter: nf_tables: fix use-after-free in nf_tables_addchain()

nf_tables_addchain() publishes the chain to table->chains via list_add_tail_rcu() (in nft_chain_add()) before registering hooks. If nf_tables_register_hook() then fails, the error path calls nft_chain_del() (list_del_rcu()) followed by nf_tables_chain_destroy() with no RCU grace period in between.

This creates two use-after-free conditions:

1) Control-plane: nf_tables_dump_chains() traverses table->chains under rcu_read_lock(). A concurrent dump can still be walking the chain when the error path frees it.

2) Packet path: for NFPROTO_INET, nf_register_net_hook() briefly installs the IPv4 hook before IPv6 registration fails. Packets entering nft…
