| 2025-03-27 | CVE-2022-49751 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: w1: fix WARNING after calling w1_process() I got the following WARNING message while removing driver(ds2482): ------------[ cut here ]------------ do not call blocking ops when !TASK_RUNNING; state=1 set at [<000000002d50bfb6>] w1_process+0x9e/0x1d0 [wire] WARNING: CPU: 0 PID: 262 at kernel/sched/core.c:9817 __might_sleep+0x98/0xa0 CPU: 0 PID: 262 Comm: w1_bus_master1 Tainted: G N 6.1.0-rc3+ #307 RIP: 0010:__might_sleep+0x98/0xa0 Call Trace: exit_signals+0x6c/0x550 do_exit+0x2b4/0x17e0 kthread_exit+0x52/0x60 kthread+0x16d/0x1e0 ret_from_fork+0x1f/0x30 The state of task is set to TASK_INTERRUPTIBLE in loop in w1_process(), set it to TASK_RUNNING when it breaks out of the loop to avoid the warning. | 5.5 |
| 2025-03-27 | CVE-2022-49757 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: EDAC/highbank: Fix memory leak in highbank_mc_probe() When devres_open_group() fails, it returns -ENOMEM without freeing memory allocated by edac_mc_alloc(). Call edac_mc_free() on the error handling path to avoid a memory leak. [ bp: Massage commit message. | 5.5 |
| 2025-03-27 | CVE-2023-52932 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: mm/swapfile: add cond_resched() in get_swap_pages() The softlockup still occurs in get_swap_pages() under memory pressure. | 5.5 |
| 2025-03-27 | CVE-2023-52936 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: kernel/irq/irqdomain.c: fix memory leak with using debugfs_lookup() When calling debugfs_lookup() the result must have dput() called on it, otherwise the memory will leak over time. | 5.5 |
| 2025-03-27 | CVE-2023-52988 | Improper Validation of Array Index vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ALSA: hda/via: Avoid potential array out-of-bound in add_secret_dac_path() snd_hda_get_connections() can return a negative error code. It may lead to accessing 'conn' array at a negative index. Found by Linux Verification Center (linuxtesting.org) with SVACE. | 7.8 |
| 2025-03-27 | CVE-2023-52989 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: firewire: fix memory leak for payload of request subaction to IEC 61883-1 FCP region This patch is fix for Linux kernel v2.6.33 or later. For request subaction to IEC 61883-1 FCP region, Linux FireWire subsystem have had an issue of use-after-free. | 5.5 |
| 2025-03-27 | CVE-2023-52993 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: x86/i8259: Mark legacy PIC interrupts with IRQ_LEVEL Baoquan reported that after triggering a crash the subsequent crash-kernel fails to boot about half of the time. | 5.5 |
| 2025-03-27 | CVE-2023-53001 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/drm_vma_manager: Add drm_vma_node_allow_once() Currently there is no easy way for a drm driver to safely check and allow drm_vma_offset_node for a drm file just once. | 5.5 |
| 2025-03-27 | CVE-2023-53008 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: cifs: fix potential memory leaks in session setup Make sure to free cifs_ses::auth_key.response before allocating it as we might end up leaking memory in reconnect or mounting. | 5.5 |
| 2025-03-27 | CVE-2023-53015 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: HID: betop: check shape of output reports betopff_init() only checks the total sum of the report counts for each report field to be at least 4, but hid_betopff_play() expects 4 report fields. A device advertising an output report with one field and 4 report counts would pass the check but crash the kernel with a NULL pointer dereference in hid_betopff_play(). | 5.5 |
