In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> btrfs: zoned: do not flag ZEROOUT on non-dirty extent buffer<br /> <br /> Btrfs clears the content of an extent buffer marked as<br /> EXTENT_BUFFER_ZONED_ZEROOUT before the bio submission. This mechanism is<br /> introduced to prevent a write hole of an extent buffer, which is once<br /> allocated, marked dirty, but turns out unnecessary and cleaned up within<br /> one transaction operation.<br /> <br /> Currently, btrfs_clear_buffer_dirty() marks the extent buffer as<br /> EXTENT_BUFFER_ZONED_ZEROOUT, and skips the entry function. If this call<br /> happens while the buffer is under IO (with the WRITEBACK flag set,<br /> without the DIRTY flag), we can add the ZEROOUT flag and clear the<br /> buffer&amp;#39;s content just before a bio submission. As a result:<br /> <br /> 1) it can lead to adding faulty delayed reference item which leads to a<br /> FS corrupted (EUCLEAN) error, and<br /> <br /> 2) it writes out cleared tree node on disk<br /> <br /> The former issue is previously discussed in [1]. The corruption happens<br /> when it runs a delayed reference update. So, on-disk data is safe.<br /> <br /> [1] https://lore.kernel.org/linux-btrfs/3f4f2a0ff1a6c818050434288925bdcf3cd719e5.1709124777.git.naohiro.aota@wdc.com/<br /> <br /> The latter one can reach on-disk data. But, as that node is already<br /> processed by btrfs_clear_buffer_dirty(), that will be invalidated in the<br /> next transaction commit anyway. So, the chance of hitting the corruption<br /> is relatively small.<br /> <br /> Anyway, we should skip flagging ZEROOUT on a non-DIRTY extent buffer, to<br /> keep the content under IO intact.

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> mmc: sdhci-msm: pervent access to suspended controller<br /> <br /> Generic sdhci code registers LED device and uses host-&gt;runtime_suspended<br /> flag to protect access to it. The sdhci-msm driver doesn&amp;#39;t set this flag,<br /> which causes a crash when LED is accessed while controller is runtime<br /> suspended. Fix this by setting the flag correctly.

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> octeontx2-af: fix the double free in rvu_npc_freemem()<br /> <br /> Clang static checker(scan-build) warning：<br /> drivers/net/ethernet/marvell/octeontx2/af/rvu_npc.c:line 2184, column 2<br /> Attempt to free released memory.<br /> <br /> npc_mcam_rsrcs_deinit() has released &amp;#39;mcam-&gt;counters.bmap&amp;#39;. Deleted this<br /> redundant kfree() to fix this double free problem.

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> Bluetooth: qca: fix info leak when fetching fw build id<br /> <br /> Add the missing sanity checks and move the 255-byte build-id buffer off<br /> the stack to avoid leaking stack data through debugfs in case the<br /> build-info reply is malformed.

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> Bluetooth: qca: fix info leak when fetching board id<br /> <br /> Add the missing sanity check when fetching the board id to avoid leaking<br /> slab data when later requesting the firmware.

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> Bluetooth: qca: add missing firmware sanity checks<br /> <br /> Add the missing sanity checks when parsing the firmware files before<br /> downloading them to avoid accessing and corrupting memory beyond the<br /> vmalloced buffer.

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> mm/userfaultfd: reset ptes when close() for wr-protected ones<br /> <br /> Userfaultfd unregister includes a step to remove wr-protect bits from all<br /> the relevant pgtable entries, but that only covered an explicit<br /> UFFDIO_UNREGISTER ioctl, not a close() on the userfaultfd itself. Cover<br /> that too. This fixes a WARN trace.<br /> <br /> The only user visible side effect is the user can observe leftover<br /> wr-protect bits even if the user close()ed on an userfaultfd when<br /> releasing the last reference of it. However hopefully that should be<br /> harmless, and nothing bad should happen even if so.<br /> <br /> This change is now more important after the recent page-table-check<br /> patch we merged in mm-unstable (446dd9ad37d0 ("mm/page_table_check:<br /> support userfault wr-protect entries")), as we&amp;#39;ll do sanity check on<br /> uffd-wp bits without vma context. So it&amp;#39;s better if we can 100%<br /> guarantee no uffd-wp bit leftovers, to make sure each report will be<br /> valid.

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> iommu/arm-smmu: Use the correct type in nvidia_smmu_context_fault()<br /> <br /> This was missed because of the function pointer indirection.<br /> <br /> nvidia_smmu_context_fault() is also installed as a irq function, and the<br /> &amp;#39;void *&amp;#39; was changed to a struct arm_smmu_domain. Since the iommu_domain<br /> is embedded at a non-zero offset this causes nvidia_smmu_context_fault()<br /> to miscompute the offset.

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> keys: Fix overwrite of key expiration on instantiation<br /> <br /> The expiry time of a key is unconditionally overwritten during<br /> instantiation, defaulting to turn it permanent. This causes a problem<br /> for DNS resolution as the expiration set by user-space is overwritten to<br /> TIME64_MAX, disabling further DNS updates. Fix this by restoring the<br /> condition that key_set_expiry is only called when the pre-parser sets a<br /> specific expiry.
