| 2024-06-19 | CVE-2024-38591 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: RDMA/hns: Fix deadlock on SRQ async events. xa_lock for SRQ table may be required in AEQ. | 5.5 |
| 2024-06-19 | CVE-2024-38597 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: eth: sungem: remove .ndo_poll_controller to avoid deadlocks Erhard reports netpoll warnings from sungem: netpoll_send_skb_on_dev(): eth0 enabled interrupts in poll (gem_start_xmit+0x0/0x398) WARNING: CPU: 1 PID: 1 at net/core/netpoll.c:370 netpoll_send_skb+0x1fc/0x20c gem_poll_controller() disables interrupts, which may sleep. We can't sleep in netpoll, it has interrupts disabled completely. Strangely, gem_poll_controller() doesn't even poll the completions, and instead acts as if an interrupt has fired so it just schedules NAPI and exits. | 5.5 |
| 2024-06-19 | CVE-2024-38598 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: md: fix resync softlockup when bitmap size is less than array size Is is reported that for dm-raid10, lvextend + lvchange --syncaction will trigger following softlockup: kernel:watchdog: BUG: soft lockup - CPU#3 stuck for 26s! [mdX_resync:6976] CPU: 7 PID: 3588 Comm: mdX_resync Kdump: loaded Not tainted 6.9.0-rc4-next-20240419 #1 RIP: 0010:_raw_spin_unlock_irq+0x13/0x30 Call Trace: <TASK> md_bitmap_start_sync+0x6b/0xf0 raid10_sync_request+0x25c/0x1b40 [raid10] md_do_sync+0x64b/0x1020 md_thread+0xa7/0x170 kthread+0xcf/0x100 ret_from_fork+0x30/0x50 ret_from_fork_asm+0x1a/0x30 And the detailed process is as follows: md_do_sync j = mddev->resync_min while (j < max_sectors) sectors = raid10_sync_request(mddev, j, &skipped) if (!md_bitmap_start_sync(..., &sync_blocks)) // md_bitmap_start_sync set sync_blocks to 0 return sync_blocks + sectors_skippe; // sectors = 0; j += sectors; // j never change Root cause is that commit 301867b1c168 ("md/raid10: check slab-out-of-bounds in md_bitmap_get_counter") return early from md_bitmap_get_counter(), without setting returned blocks. Fix this problem by always set returned blocks from md_bitmap_get_counter"(), as it used to be. Noted that this patch just fix the softlockup problem in kernel, the case that bitmap size doesn't match array size still need to be fixed. | 5.5 |
| 2024-06-19 | CVE-2024-38600 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ALSA: Fix deadlocks with kctl removals at disconnection In snd_card_disconnect(), we set card->shutdown flag at the beginning, call callbacks and do sync for card->power_ref_sleep waiters at the end. | 5.5 |
| 2024-06-19 | CVE-2024-38602 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ax25: Fix reference count leak issues of ax25_dev The ax25_addr_ax25dev() and ax25_dev_device_down() exist a reference count leak issue of the object "ax25_dev". Memory leak issue in ax25_addr_ax25dev(): The reference count of the object "ax25_dev" can be increased multiple times in ax25_addr_ax25dev(). | 5.5 |
| 2024-06-19 | CVE-2024-38603 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drivers/perf: hisi: hns3: Actually use devm_add_action_or_reset() pci_alloc_irq_vectors() allocates an irq vector. | 5.5 |
| 2024-06-19 | CVE-2024-38608 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix netif state handling mlx5e_suspend cleans resources only if netif_device_present() returns true. | 5.5 |
| 2024-06-18 | CVE-2024-36976 | Improper Locking vulnerability in Linux Kernel 6.9/6.9.1 In the Linux kernel, the following vulnerability has been resolved: Revert "media: v4l2-ctrls: show all owned controls in log_status" This reverts commit 9801b5b28c6929139d6fceeee8d739cc67bb2739. This patch introduced a potential deadlock scenario: [Wed May 8 10:02:06 2024] Possible unsafe locking scenario: [Wed May 8 10:02:06 2024] CPU0 CPU1 [Wed May 8 10:02:06 2024] ---- ---- [Wed May 8 10:02:06 2024] lock(vivid_ctrls:1620:(hdl_vid_cap)->_lock); [Wed May 8 10:02:06 2024] lock(vivid_ctrls:1608:(hdl_user_vid)->_lock); [Wed May 8 10:02:06 2024] lock(vivid_ctrls:1620:(hdl_vid_cap)->_lock); [Wed May 8 10:02:06 2024] lock(vivid_ctrls:1608:(hdl_user_vid)->_lock); For now just revert. | 5.5 |
| 2024-06-08 | CVE-2024-36965 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: remoteproc: mediatek: Make sure IPI buffer fits in L2TCM The IPI buffer location is read from the firmware that we load to the System Companion Processor, and it's not granted that both the SRAM (L2TCM) size that is defined in the devicetree node is large enough for that, and while this is especially true for multi-core SCP, it's still useful to check on single-core variants as well. Failing to perform this check may make this driver perform R/W operations out of the L2TCM boundary, resulting (at best) in a kernel panic. To fix that, check that the IPI buffer fits, otherwise return a failure and refuse to boot the relevant SCP core (or the SCP at all, if this is single core). | 5.5 |
| 2024-06-08 | CVE-2024-36967 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: KEYS: trusted: Fix memory leak in tpm2_key_encode() 'scratch' is never freed. | 5.5 |
