| 2024-04-28 | CVE-2022-48659 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: mm/slub: fix to return errno if kmalloc() fails In create_unique_id(), kmalloc(, GFP_KERNEL) can fail due to out-of-memory, if it fails, return errno correctly rather than triggering panic via BUG_ON(); kernel BUG at mm/slub.c:5893!

| 2024-04-28 | CVE-2024-26928 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: smb: client: fix potential UAF in cifs_debug_files_proc_show() Skip sessions that are being teared down (status == SES_EXITING) to avoid UAF. | 7.8 |
| 2024-04-17 | CVE-2024-26910 | Race Condition vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: netfilter: ipset: fix performance regression in swap operation The patch "netfilter: ipset: fix race condition between swap/destroy and kernel side add/del/test", commit 28628fa9 fixes a race condition. But the synchronize_rcu() added to the swap function unnecessarily slows it down: it can safely be moved to destroy and use call_rcu() instead. Eric Dumazet pointed out that simply calling the destroy functions as rcu callback does not work: sets with timeout use garbage collectors which need cancelling at destroy which can wait. | 4.7 |
| 2024-04-17 | CVE-2023-52644 | In the Linux kernel, the following vulnerability has been resolved: wifi: b43: Stop/wake correct queue in DMA Tx path when QoS is disabled When QoS is disabled, the queue priority value will not map to the correct ieee80211 queue since there is only one queue. | 6.3 |

| 2024-04-17 | CVE-2024-26878 | NULL Pointer Dereference vulnerability in multiple products In the Linux kernel, the following vulnerability has been resolved: quota: Fix potential NULL pointer dereference Below race may cause NULL pointer dereference P1 P2 dquot_free_inode quota_off drop_dquot_ref remove_dquot_ref dquots = i_dquot(inode) dquots = i_dquot(inode) srcu_read_lock dquots[cnt]) != NULL (1) dquots[type] = NULL (2) spin_lock(&dquots[cnt]->dq_dqb_lock) (3) .... If dquot_free_inode(or other routines) checks inode's quota pointers (1) before quota_off sets it to NULL(2) and use it (3) after that, NULL pointer dereference will be triggered. So let's fix it by using a temporary pointer to avoid this issue. | 4.7 |
| 2024-04-17 | CVE-2024-26898 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: aoe: fix the potential use-after-free problem in aoecmd_cfg_pkts This patch is against CVE-2023-6270. | 7.8 |
| 2024-04-17 | CVE-2024-26902 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: perf: RISCV: Fix panic on pmu overflow handler (1 << idx) of int is not desired when setting bits in unsigned long overflowed_ctrs, use BIT() instead. | 5.5 |
| 2024-04-17 | CVE-2024-26903 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: Bluetooth: rfcomm: Fix null-ptr-deref in rfcomm_check_security During our fuzz testing of the connection and disconnection process at the RFCOMM layer, we discovered this bug. | 5.5 |
