| 2024-08-17 | CVE-2024-42262 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/v3d: Fix potential memory leak in the performance extension If fetching of userspace memory fails during the main loop, all drm sync objs looked up until that point will be leaked because of the missing drm_syncobj_put. Fix it by exporting and using a common cleanup helper. (cherry picked from commit 484de39fa5f5b7bd0c5f2e2c5265167250ef7501) | 5.5 |
| 2024-08-17 | CVE-2024-42263 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/v3d: Fix potential memory leak in the timestamp extension If fetching of userspace memory fails during the main loop, all drm sync objs looked up until that point will be leaked because of the missing drm_syncobj_put. Fix it by exporting and using a common cleanup helper. (cherry picked from commit 753ce4fea62182c77e1691ab4f9022008f25b62e) | 5.5 |
| 2024-08-17 | CVE-2024-42268 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Fix missing lock on sync reset reload On sync reset reload work, when remote host updates devlink on reload actions performed on that host, it misses taking devlink lock before calling devlink_remote_reload_actions_performed() which results in triggering lock assert like the following: WARNING: CPU: 4 PID: 1164 at net/devlink/core.c:261 devl_assert_locked+0x3e/0x50 … CPU: 4 PID: 1164 Comm: kworker/u96:6 Tainted: G S W 6.10.0-rc2+ #116 Hardware name: Supermicro SYS-2028TP-DECTR/X10DRT-PT, BIOS 2.0 12/18/2015 Workqueue: mlx5_fw_reset_events mlx5_sync_reset_reload_work [mlx5_core] RIP: 0010:devl_assert_locked+0x3e/0x50 … Call Trace: <TASK> ? __warn+0xa4/0x210 ? devl_assert_locked+0x3e/0x50 ? report_bug+0x160/0x280 ? handle_bug+0x3f/0x80 ? exc_invalid_op+0x17/0x40 ? asm_exc_invalid_op+0x1a/0x20 ? devl_assert_locked+0x3e/0x50 devlink_notify+0x88/0x2b0 ? mlx5_attach_device+0x20c/0x230 [mlx5_core] ? __pfx_devlink_notify+0x10/0x10 ? process_one_work+0x4b6/0xbb0 process_one_work+0x4b6/0xbb0 […] | 5.5 |
| 2024-08-17 | CVE-2024-42269 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: netfilter: iptables: Fix potential null-ptr-deref in ip6table_nat_table_init(). ip6table_nat_table_init() accesses net->gen->ptr[ip6table_nat_net_ops.id], but the function is exposed to user space before the entry is allocated via register_pernet_subsys(). Let's call register_pernet_subsys() before xt_register_template(). | 5.5 |
| 2024-08-17 | CVE-2024-42270 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: netfilter: iptables: Fix null-ptr-deref in iptable_nat_table_init(). We had a report that iptables-restore sometimes triggered null-ptr-deref at boot time. | 5.5 |
| 2024-08-17 | CVE-2024-42272 | Use of Uninitialized Resource vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: sched: act_ct: take care of padding in struct zones_ht_key Blamed commit increased lookup key size from 2 bytes to 16 bytes, because zones_ht_key got a struct net pointer. Make sure rhashtable_lookup() is not using the padding bytes which are not initialized.

| 2024-08-17 | CVE-2024-42277 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: iommu: sprd: Avoid NULL deref in sprd_iommu_hw_en In sprd_iommu_cleanup() before calling function sprd_iommu_hw_en() dom->sdev is equal to NULL, which leads to null dereference. Found by Linux Verification Center (linuxtesting.org) with SVACE. | 5.5 |
| 2024-08-17 | CVE-2024-42278 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ASoC: TAS2781: Fix tasdev_load_calibrated_data() This function has a reversed if statement so it's either a no-op or it leads to a NULL dereference. | 5.5 |
| 2024-08-17 | CVE-2024-42282 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net: mediatek: Fix potential NULL pointer dereference in dummy net_device handling Move the freeing of the dummy net_device from mtk_free_dev() to mtk_remove(). Previously, if alloc_netdev_dummy() failed in mtk_probe(), eth->dummy_dev would be NULL. | 5.5 |
| 2024-08-17 | CVE-2024-42283 | Use of Uninitialized Resource vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net: nexthop: Initialize all fields in dumped nexthops struct nexthop_grp contains two reserved fields that are not initialized by nla_put_nh_group(), and carry garbage. | 5.5 |
