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...

CVE-2022-49453 soc: ti: ti_sci_pm_domains: Check for null return of devm_kcalloc

In the Linux kernel, the following vulnerability has been resolved: soc: ti: tiscipmdomains: Check for null return of devmkcalloc The allocation funciton devmkcalloc may fail and return a null pointer, which would cause a null-pointer dereference later. It might be better to check it and directly...
