https://notcve.org/view.php?id=CVE-2024-42231
In the Linux kernel, the following vulnerability has been resolved: btrfs: zoned: fix calc_available_free_space() for zoned mode calc_available_free_space() returns the total size of metadata (or system) block groups, which can be allocated from unallocated disk space. The logic is wrong on zoned mode in two places. First, the calculation of data_chunk_size is wrong. We always allocate one zone as one chunk, and no partial allocation of a zone. So, we should use zone_size (= data_sinfo->chunk_size) as it is. Second, the result "avail" may not be zone aligned. Since we always allocate one zone as one chunk on zoned mode, returning non-zone size aligned bytes will result in less pressure on the async metadata reclaim process. This is serious for the nearly full state with a large zone size device. Allowing over-commit too much will result in less async reclaim work and end up in ENOSPC. • https://git.kernel.org/stable/c/cb6cbab79055ca207ad88bc54226b48ececdcef0 https://git.kernel.org/stable/c/8548903b1999bba02a2b894ad750ab8eb1f40307 https://git.kernel.org/stable/c/64d2c847ba380e07b9072d65a50aa6469d2aa43f •

https://notcve.org/view.php?id=CVE-2024-42230
In the Linux kernel, the following vulnerability has been resolved: powerpc/pseries: Fix scv instruction crash with kexec kexec on pseries disables AIL (reloc_on_exc), required for scv instruction support, before other CPUs have been shut down. This means they can execute scv instructions after AIL is disabled, which causes an interrupt at an unexpected entry location that crashes the kernel. Change the kexec sequence to disable AIL after other CPUs have been brought down. As a refresher, the real-mode scv interrupt vector is 0x17000, and the fixed-location head code probably couldn't easily deal with implementing such high addresses so it was just decided not to support that interrupt at all. • https://git.kernel.org/stable/c/7fa95f9adaee7e5cbb195d3359741120829e488b https://git.kernel.org/stable/c/c550679d604798d9fed8a5b2bb5693448a25407c https://git.kernel.org/stable/c/d10e3c39001e9194b9a1bfd6979bd3fa19dccdc5 https://git.kernel.org/stable/c/8c6506616386ce37e59b2745fc481c6713fae4f3 https://git.kernel.org/stable/c/21a741eb75f80397e5f7d3739e24d7d75e619011 •
