29 Jul 2024 — In the Linux kernel, the following vulnerability has been resolved: filelock: fix potential use-after-free in posix_lock_inode Light Hsieh reported a KASAN UAF warning in trace_posix_lock_inode(). The request pointer had been changed earlier to point to a lock entry that was added to the inode's list. However, before the tracepoint could fire, another task raced in and freed that lock. Fix this by moving the tracepoint inside the spinlock, which should ensure that this doesn't happen. In the Linux kernel, t... • https://git.kernel.org/stable/c/117fb80cd1e63c419c7a221ce070becb4bfc7b6d • CWE-416: Use After Free •

29 Jul 2024 — In the Linux kernel, the following vulnerability has been resolved: i40e: Fix XDP program unloading while removing the driver The commit 6533e558c650 ("i40e: Fix reset path while removing the driver") introduced a new PF state "__I40E_IN_REMOVE" to block modifying the XDP program while the driver is being removed. Unfortunately, such a change is useful only if the ".ndo_bpf()" callback was called out of the rmmod context because unloading the existing XDP program is also a part of driver removing procedure.... • https://git.kernel.org/stable/c/b82364abc54b19829b26459989d2781fc4822c28 •

29 Jul 2024 — In the Linux kernel, the following vulnerability has been resolved: bpf: Defer work in bpf_timer_cancel_and_free Currently, the same case as previous patch (two timer callbacks trying to cancel each other) can be invoked through bpf_map_update_elem as well, or more precisely, freeing map elements containing timers. Since this relies on hrtimer_cancel as well, it is prone to the same deadlock situation as the previous patch. It would be sufficient to use hrtimer_try_to_cancel to fix this problem, as the time... • https://git.kernel.org/stable/c/b00628b1c7d595ae5b544e059c27b1f5828314b4 •

29 Jul 2024 — In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: prefer nft_chain_validate nft_chain_validate already performs loop detection because a cycle will result in a call stack overflow (ctx->level >= NFT_JUMP_STACK_SIZE). It also follows maps via ->validate callback in nft_lookup, so there appears no reason to iterate the maps again. nf_tables_check_loops() and all its helper functions can be removed. This improves ruleset load time significantly, from 23s down to 12s. Thi... • https://git.kernel.org/stable/c/20a69341f2d00cd042e81c82289fba8a13c05a25 • CWE-121: Stack-based Buffer Overflow •

In udp_v[46]_early_demux() and sk_lookup(), we do not touch the refcount of the looked-up sk and use sock_pfree() as skb->destructor, so we check SOCK_RCU_FREE to ensure that the sk is safe to access during the RCU grace period. Currently, SOCK_RCU_FREE is flagged for a bound socket after being put into the hash table.
