| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2025-02-26 | CVE-2022-49450 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix listen() setting the bar too high for the prealloc rings AF_RXRPC's listen() handler lets you set the backlog up to 32 (if you bump up the sysctl), but whilst the preallocation circular buffers have 32 slots in them, one of them has to be a dead slot because we're using CIRC_CNT(). This means that listen(rxrpc_sock, 32) will cause an oops when the socket is closed because rxrpc_service_prealloc_one() allocated one too many calls and rxrpc_discard_prealloc() won't then be able to get rid of them because it'll think the ring is empty. | 5.5 |
| 2025-02-26 | CVE-2022-49451 | Integer Overflow or Wraparound vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: firmware: arm_scmi: Fix list protocols enumeration in the base protocol While enumerating protocols implemented by the SCMI platform using BASE_DISCOVER_LIST_PROTOCOLS, the number of returned protocols is currently validated in an improper way since the check employs a sum between unsigned integers that could overflow and cause the check itself to be silently bypassed if the returned value 'loop_num_ret' is big enough. Fix the validation avoiding the addition. | 5.5 |
| 2025-02-26 | CVE-2022-49453 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: soc: ti: ti_sci_pm_domains: Check for null return of devm_kcalloc The allocation funciton devm_kcalloc may fail and return a null pointer, which would cause a null-pointer dereference later. It might be better to check it and directly return -ENOMEM just like the usage of devm_kcalloc in previous code. | 5.5 |
| 2025-02-26 | CVE-2022-49455 | Double Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: misc: ocxl: fix possible double free in ocxl_file_register_afu info_release() will be called in device_unregister() when info->dev's reference count is 0. | 7.8 |
| 2025-02-26 | CVE-2022-49457 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ARM: versatile: Add missing of_node_put in dcscb_init The device_node pointer is returned by of_find_compatible_node with refcount incremented. | 5.5 |
| 2025-02-26 | CVE-2022-49459 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: thermal/drivers/broadcom: Fix potential NULL dereference in sr_thermal_probe platform_get_resource() may return NULL, add proper check to avoid potential NULL dereferencing. | 5.5 |
| 2025-02-26 | CVE-2022-49462 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/msm/a6xx: Fix refcount leak in a6xx_gpu_init of_parse_phandle() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. a6xx_gmu_init() passes the node to of_find_device_by_node() and of_dma_configure(), of_find_device_by_node() will takes its reference, of_dma_configure() doesn't need the node after usage. Add missing of_node_put() to avoid refcount leak. | 5.5 |
| 2025-02-26 | CVE-2022-49467 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm: msm: fix possible memory leak in mdp5_crtc_cursor_set() drm_gem_object_lookup will call drm_gem_object_get inside. | 5.5 |
| 2025-02-26 | CVE-2022-49468 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: thermal/core: Fix memory leak in __thermal_cooling_device_register() I got memory leak as follows when doing fault injection test: unreferenced object 0xffff888010080000 (size 264312): comm "182", pid 102533, jiffies 4296434960 (age 10.100s) hex dump (first 32 bytes): 00 00 00 00 ad 4e ad de ff ff ff ff 00 00 00 00 .....N.......... ff ff ff ff ff ff ff ff 40 7f 1f b9 ff ff ff ff ........@....... backtrace: [<0000000038b2f4fc>] kmalloc_order_trace+0x1d/0x110 mm/slab_common.c:969 [<00000000ebcb8da5>] __kmalloc+0x373/0x420 include/linux/slab.h:510 [<0000000084137f13>] thermal_cooling_device_setup_sysfs+0x15d/0x2d0 include/linux/slab.h:586 [<00000000352b8755>] __thermal_cooling_device_register+0x332/0xa60 drivers/thermal/thermal_core.c:927 [<00000000fb9f331b>] devm_thermal_of_cooling_device_register+0x6b/0xf0 drivers/thermal/thermal_core.c:1041 [<000000009b8012d2>] max6650_probe.cold+0x557/0x6aa drivers/hwmon/max6650.c:211 [<00000000da0b7e04>] i2c_device_probe+0x472/0xac0 drivers/i2c/i2c-core-base.c:561 If device_register() fails, thermal_cooling_device_destroy_sysfs() need be called to free the memory allocated in thermal_cooling_device_setup_sysfs(). | 5.5 |
