| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2025-02-26 | CVE-2022-49329 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: vduse: Fix NULL pointer dereference on sysfs access The control device has no drvdata. | 5.5 |
| 2025-02-26 | CVE-2022-49332 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Address NULL pointer dereference after starget_to_rport() Calls to starget_to_rport() may return NULL. | 5.5 |
| 2025-02-26 | CVE-2022-49335 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/cs: make commands with 0 chunks illegal behaviour. Submitting a cs with 0 chunks, causes an oops later, found trying to execute the wrong userspace driver. MESA_LOADER_DRIVER_OVERRIDE=v3d glxinfo [172536.665184] BUG: kernel NULL pointer dereference, address: 00000000000001d8 [172536.665188] #PF: supervisor read access in kernel mode [172536.665189] #PF: error_code(0x0000) - not-present page [172536.665191] PGD 6712a0067 P4D 6712a0067 PUD 5af9ff067 PMD 0 [172536.665195] Oops: 0000 [#1] SMP NOPTI [172536.665197] CPU: 7 PID: 2769838 Comm: glxinfo Tainted: P O 5.10.81 #1-NixOS [172536.665199] Hardware name: To be filled by O.E.M. | 5.5 |
| 2025-02-26 | CVE-2022-49445 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: pinctrl: renesas: core: Fix possible null-ptr-deref in sh_pfc_map_resources() 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-2022-49448 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: soc: bcm: Check for NULL return of devm_kzalloc() As the potential failure of allocation, devm_kzalloc() may return NULL. | 5.5 |
| 2025-02-26 | CVE-2022-49449 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: pinctrl: renesas: rzn1: Fix possible null-ptr-deref in sh_pfc_map_resources() 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-2022-49450 | 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-2022-49453 | 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-2022-49459 | 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-2022-49472 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net: phy: micrel: Allow probing without .driver_data Currently, if the .probe element is present in the phy_driver structure and the .driver_data is not, a NULL pointer dereference happens. Allow passing .probe without .driver_data by inserting NULL checks for priv->type. | 5.5 |
