| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2025-02-26 | CVE-2022-49494 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: mtd: rawnand: cadence: fix possible null-ptr-deref in cadence_nand_dt_probe() It will cause null-ptr-deref when using 'res', if platform_get_resource() returns NULL, so move using 'res' after devm_ioremap_resource() that will check it to avoid null-ptr-deref. And use devm_platform_get_and_ioremap_resource() to simplify code. | 5.5 |
| 2025-02-26 | CVE-2022-49495 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/msm/hdmi: check return value after calling platform_get_resource_byname() It will cause null-ptr-deref if platform_get_resource_byname() returns NULL, we need check the return value. Patchwork: https://patchwork.freedesktop.org/patch/482992/ | 5.5 |
| 2025-02-26 | CVE-2022-49496 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: media: mediatek: vcodec: prevent kernel crash when rmmod mtk-vcodec-dec.ko If the driver support subdev mode, the parameter "dev->pm.dev" will be NULL in mtk_vcodec_dec_remove. | 5.5 |
| 2025-02-26 | CVE-2022-49497 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net: remove two BUG() from skb_checksum_help() I have a syzbot report that managed to get a crash in skb_checksum_help() If syzbot can trigger these BUG(), it makes sense to replace them with more friendly WARN_ON_ONCE() since skb_checksum_help() can instead return an error code. Note that syzbot will still crash there, until real bug is fixed. | 5.5 |
| 2025-02-26 | CVE-2022-49498 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: Check for null pointer of pointer substream before dereferencing it Pointer substream is being dereferenced on the assignment of pointer card before substream is being null checked with the macro PCM_RUNTIME_CHECK. Although PCM_RUNTIME_CHECK calls BUG_ON, it still is useful to perform the the pointer check before card is assigned. | 5.5 |
| 2025-02-26 | CVE-2022-49499 | NULL Pointer Dereference vulnerability in Linux Kernel 5.18.1/5.18.2 In the Linux kernel, the following vulnerability has been resolved: drm/msm: Fix null pointer dereferences without iommu Check if 'aspace' is set before using it as it will stay null without IOMMU, such as on msm8974. | 5.5 |
| 2025-02-26 | CVE-2022-49502 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: media: rga: fix possible memory leak in rga_probe rga->m2m_dev needs to be freed when rga_probe fails. | 5.5 |
| 2025-02-26 | CVE-2022-49507 | Use of Uninitialized Resource vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: regulator: da9121: Fix uninit-value in da9121_assign_chip_model() KASAN report slab-out-of-bounds in __regmap_init as follows: BUG: KASAN: slab-out-of-bounds in __regmap_init drivers/base/regmap/regmap.c:841 Read of size 1 at addr ffff88803678cdf1 by task xrun/9137 CPU: 0 PID: 9137 Comm: xrun Tainted: G W 5.18.0-rc2 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.13.0-1ubuntu1.1 04/01/2014 Call Trace: <TASK> dump_stack_lvl+0xe8/0x15a lib/dump_stack.c:88 print_report.cold+0xcd/0x69b mm/kasan/report.c:313 kasan_report+0x8e/0xc0 mm/kasan/report.c:491 __regmap_init+0x4540/0x4ba0 drivers/base/regmap/regmap.c:841 __devm_regmap_init+0x7a/0x100 drivers/base/regmap/regmap.c:1266 __devm_regmap_init_i2c+0x65/0x80 drivers/base/regmap/regmap-i2c.c:394 da9121_i2c_probe+0x386/0x6d1 drivers/regulator/da9121-regulator.c:1039 i2c_device_probe+0x959/0xac0 drivers/i2c/i2c-core-base.c:563 This happend when da9121 device is probe by da9121_i2c_id, but with invalid dts. | 5.5 |
| 2025-02-26 | CVE-2022-49508 | Double Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: HID: elan: Fix potential double free in elan_input_configured 'input' is a managed resource allocated with devm_input_allocate_device(), so there is no need to call input_free_device() explicitly or there will be a double free. According to the doc of devm_input_allocate_device(): * Managed input devices do not need to be explicitly unregistered or * freed as it will be done automatically when owner device unbinds from * its driver (or binding fails). | 7.8 |
| 2025-02-26 | CVE-2022-49510 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/omap: fix NULL but dereferenced coccicheck error Fix the following coccicheck warning: ./drivers/gpu/drm/omapdrm/omap_overlay.c:89:22-25: ERROR: r_ovl is NULL but dereferenced. Here should be ovl->idx rather than r_ovl->idx. | 5.5 |
