CVE-2022-49608

CVE-2022-49608 pertains to the Linux kernel pinctrl: ralink subsystem. A allocation failure can make data->domains NULL, leading to a NULL pointer dereference. The described fix adds a null return check after devm_kcalloc and suggests returning -ENOMEM immediately instead of manually freeing d...

CVE-2022-49608 pinctrl: ralink: Check for null return of devm_kcalloc

In the Linux kernel, the following vulnerability has been resolved: pinctrl: ralink: Check for null return of devmkcalloc Because of the possible failure of the allocation, data-domains might be NULL pointer and will cause the dereference of the NULL pointer later. Therefore, it might be better t...

CVE-2022-49500 wl1251: dynamically allocate memory used for DMA

In the Linux kernel, the following vulnerability has been resolved: wl1251: dynamically allocate memory used for DMA With introduction of vmap'ed stacks, stack parameters can no longer be used for DMA and now leads to kernel panic. It happens at several places for the wl1251 e.g. when accessed...

CVE-2022-49500

CVE-2022-49500 concerns the wl1251 DMA memory handling in the Linux kernel. With the switch to vmap’ed stacks, stack parameters can no longer be used for DMA, which could trigger a kernel panic at multiple wl1251 locations (e.g., via SDIO), rendering devices like OpenPandora unusable. The fixed a...

CVE-2022-49453

Summary (CVE-2022-49453) : In the Linux kernel, the TI SoC power-domain driver (soc: ti: ti_sci_pm_domains) might dereference a NULL pointer if devm_kcalloc returns NULL. The recommended fix is to check the allocation result and return -ENOMEM, mirroring the handling in earlier code paths. The is...
