https://notcve.org/view.php?id=CVE-2024-40963
In the Linux kernel, the following vulnerability has been resolved: mips: bmips: BCM6358: make sure CBR is correctly set It was discovered that some device have CBR address set to 0 causing kernel panic when arch_sync_dma_for_cpu_all is called. This was notice in situation where the system is booted from TP1 and BMIPS_GET_CBR() returns 0 instead of a valid address and !!(read_c0_brcm_cmt_local() & (1 << 31)); not failing. The current check whether RAC flush should be disabled or not are not enough hence lets check if CBR is a valid address or not. • https://git.kernel.org/stable/c/d65de5ee8b72868fbbbd39ca73017d0e526fa13a https://git.kernel.org/stable/c/47a449ec09b4479b89dcc6b27ec3829fc82ffafb https://git.kernel.org/stable/c/65b723644294f1d79770704162c0e8d1f700b6f1 https://git.kernel.org/stable/c/2cdbcff99f15db86a10672fb220379a1ae46ccae https://git.kernel.org/stable/c/ab327f8acdf8d06601fbf058859a539a9422afff https://git.kernel.org/stable/c/288c96aa5b5526cd4a946e84ef85e165857693b5 https://git.kernel.org/stable/c/10afe5f7d30f6fe50c2b1177549d0e04921fc373 https://git.kernel.org/stable/c/36d771ce6028b886e18a4a8956a5d2368 •
