CVE-2022-49623

CVE-2022-49623 : In the Linux kernel, the powerpc/xive/spapr path allocated a bitmap using bits units instead of the required long-sized units, causing a KASAN slab-out-of-bounds access on the 8-byte bitmap. The stack trace shows the access occurs during CPU setup for SMP, with the fault tied to ...

CVE-2022-49526

CVE-2022-49526 - Linux kernel md/bitmap issue : In clustered MD (md-cluster) setups, the code path md_bitmap_read_sb can permit a faulty bitmap to pass sanity checks, allowing the chunksize to be assigned even when the bitmap data is invalid. This leads to a division error (DIV_ROUND_UP_SECTOR_T)...
