CVSS: -EPSS: 0%CPEs: 3EXPL: 0CVE-2022-48833 – btrfs: skip reserved bytes warning on unmount after log cleanup failure
https://notcve.org/view.php?id=CVE-2022-48833
In the Linux kernel, the following vulnerability has been resolved: btrfs: skip reserved bytes warning on unmount after log cleanup failure After the recent changes made by commit c2e39305299f01 ("btrfs: clear extent buffer uptodate when we fail to write it") and its followup fix, commit 651740a5024117 ("btrfs: check WRITE_ERR when trying to read an extent buffer"), we can now end up not cleaning up space reservations of log tree extent buffers after a transaction abort happens, as well as not cleaning up still dirty extent buffers. This happens because if writeback for a log tree extent buffer failed, then we have cleared the bit EXTENT_BUFFER_UPTODATE from the extent buffer and we have also set the bit EXTENT_BUFFER_WRITE_ERR on it. Later on, when trying to free the log tree with free_log_tree(), which iterates over the tree, we can end up getting an -EIO error when trying to read a node or a leaf, since read_extent_buffer_pages() returns -EIO if an extent buffer does not have EXTENT_BUFFER_UPTODATE set and has the EXTENT_BUFFER_WRITE_ERR bit set. Getting that -EIO means that we return immediately as we can not iterate over the entire tree. In that case we never update the reserved space for an extent buffer in the respective block group and space_info object. When this happens we get the following traces when unmounting the fs: [174957.284509] BTRFS: error (device dm-0) in cleanup_transaction:1913: errno=-5 IO failure [174957.286497] BTRFS: error (device dm-0) in free_log_tree:3420: errno=-5 IO failure [174957.399379] ------------[ cut here ]------------ [174957.402497] WARNING: CPU: 2 PID: 3206883 at fs/btrfs/block-group.c:127 btrfs_put_block_group+0x77/0xb0 [btrfs] [174957.407523] Modules linked in: btrfs overlay dm_zero (...)

https://notcve.org/view.php?id=CVE-2022-48829
In the Linux kernel, the following vulnerability has been resolved: NFSD: Fix NFSv3 SETATTR/CREATE's handling of large file sizes iattr::ia_size is a loff_t, so these NFSv3 procedures must be careful to deal with incoming client size values that are larger than s64_max without corrupting the value. Silently capping the value results in storing a different value than the client passed in which is unexpected behavior, so remove the min_t() check in decode_sattr3(). Note that RFC 1813 permits only the WRITE procedure to return NFS3ERR_FBIG. We believe that NFSv3 reference implementations also return NFS3ERR_FBIG when ia_size is too large. • https://git.kernel.org/stable/c/a231ae6bb50e7c0a9e9efd7b0d10687f1d71b3a3 https://git.kernel.org/stable/c/37f2d2cd8eadddbbd9c7bda327a9393399b2f89b https://git.kernel.org/stable/c/aa9051ddb4b378bd22e72a67bc77b9fc1482c5f0 https://git.kernel.org/stable/c/a648fdeb7c0e17177a2280344d015dba3fbe3314 https://access.redhat.com/security/cve/CVE-2022-48829 https://bugzilla.redhat.com/show_bug.cgi?id=2298168 • CWE-253: Incorrect Check of Function Return Value •

https://notcve.org/view.php?id=CVE-2022-48828
In the Linux kernel, the following vulnerability has been resolved: NFSD: Fix ia_size underflow iattr::ia_size is a loff_t, which is a signed 64-bit type. NFSv3 and NFSv4 both define file size as an unsigned 64-bit type. Thus there is a range of valid file size values an NFS client can send that is already larger than Linux can handle. Currently decode_fattr4() dumps a full u64 value into ia_size. If that value happens to be larger than S64_MAX, then ia_size underflows. I'm about to fix up the NFSv3 behavior as well, so let's catch the underflow in the common code path: nfsd_setattr(). • https://git.kernel.org/stable/c/38d02ba22e43b6fc7d291cf724bc6e3b7be6626b https://git.kernel.org/stable/c/8e0ecaf7a7e57b30284d6b3289cc436100fadc48 https://git.kernel.org/stable/c/da22ca1ad548429d7822011c54cfe210718e0aa7 https://git.kernel.org/stable/c/e6faac3f58c7c4176b66f63def17a34232a17b0e https://access.redhat.com/security/cve/CVE-2022-48828 https://bugzilla.redhat.com/show_bug.cgi?id=2298167 •
