CVE-2022-48925 – RDMA/cma: Do not change route.addr.src_addr outside state checks
https://notcve.org/view.php?id=CVE-2022-48925
22 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: RDMA/cma: Do not change route.addr.src_addr outside state checks If the state is not idle then resolve_prepare_src() should immediately fail and no change to global state should happen. However, it unconditionally overwrites the src_addr trying to build a temporary any address. For instance if the state is already RDMA_CM_LISTEN then this will corrupt the src_addr and would cause the test in cma_cancel_operation(): if (cma_any_addr(cma_src_... • https://git.kernel.org/stable/c/732d41c545bb359cbb8c94698bdc1f8bcf82279c •

22 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: btrfs: prevent copying too big compressed lzo segment Compressed length can be corrupted to be a lot larger than memory we have allocated for buffer. This will cause memcpy in copy_compressed_segment to write outside of allocated memory. This mostly results in stuck read syscall but sometimes when using btrfs send can get #GP kernel: general protection fault, probably for non-canonical address 0x841551d5c1000: 0000 [#1] PREEMPT SMP NOPTI ke... • https://git.kernel.org/stable/c/8df508b7a44cd8110c726057cd28e8f8116885eb •
