CVE-2024-49965 – ocfs2: remove unreasonable unlock in ocfs2_read_blocks
https://notcve.org/view.php?id=CVE-2024-49965
In the Linux kernel, the following vulnerability has been resolved: ocfs2: remove unreasonable unlock in ocfs2_read_blocks Patch series "Misc fixes for ocfs2_read_blocks", v5. This series contains 2 fixes for ocfs2_read_blocks(). The first patch fix the issue reported by syzbot, which detects bad unlock balance in ocfs2_read_blocks(). The second patch fixes an issue reported by Heming Zhao when reviewing above fix. This patch (of 2): There was a lock release before exiting, so remove the unreasonable unlock. • https://git.kernel.org/stable/c/cf76c78595ca87548ca5e45c862ac9e0949c4687 https://git.kernel.org/stable/c/01f93d5e36753fc4d06ec67f05ce78c9c6f2dd56 https://git.kernel.org/stable/c/65cbd1279f4b999d56a838344a30642db24cd215 https://git.kernel.org/stable/c/97e1db17bc1ef4c2e1789bc9323c7be44fba53f8 https://git.kernel.org/stable/c/6c150df9c2e80b5cf86f5a0d98beb7390ad63bfc https://git.kernel.org/stable/c/3f1ca6ba5452d53c598a45d21267a2c0c221eef3 https://git.kernel.org/stable/c/f55a33fe0fb5274ef185fd61947cf142138958af https://git.kernel.org/stable/c/81aba693b129e82e11bb54f569504d943 •

CVE-2024-49964 – mm/hugetlb: fix memfd_pin_folios free_huge_pages leak
https://notcve.org/view.php?id=CVE-2024-49964
In the Linux kernel, the following vulnerability has been resolved: mm/hugetlb: fix memfd_pin_folios free_huge_pages leak memfd_pin_folios followed by unpin_folios fails to restore free_huge_pages if the pages were not already faulted in, because the folio refcount for pages created by memfd_alloc_folio never goes to 0. memfd_pin_folios needs another folio_put to undo the folio_try_get below: memfd_alloc_folio() alloc_hugetlb_folio_nodemask() dequeue_hugetlb_folio_nodemask() dequeue_hugetlb_folio_node_exact() folio_ref_unfreeze(folio, 1); ; adds 1 refcount folio_try_get() ; adds 1 refcount hugetlb_add_to_page_cache() ; adds 512 refcount (on x86) With the fix, after memfd_pin_folios + unpin_folios, the refcount for the (unfaulted) page is 512, which is correct, as the refcount for a faulted unpinned page is 513. • https://git.kernel.org/stable/c/89c1905d9c140372b7f50ef48f42378cf85d9bc5 https://git.kernel.org/stable/c/59e081ff2e91bbf19b8c1ecb75b031f778858383 https://git.kernel.org/stable/c/c56b6f3d801d7ec8965993342bdd9e2972b6cb8e •

CVE-2024-49963 – mailbox: bcm2835: Fix timeout during suspend mode
https://notcve.org/view.php?id=CVE-2024-49963
In the Linux kernel, the following vulnerability has been resolved: mailbox: bcm2835: Fix timeout during suspend mode During noirq suspend phase the Raspberry Pi power driver suffer of firmware property timeouts. The reason is that the IRQ of the underlying BCM2835 mailbox is disabled and rpi_firmware_property_list() will always run into a timeout [1]. Since the VideoCore side isn't consider as a wakeup source, set the IRQF_NO_SUSPEND flag for the mailbox IRQ in order to keep it enabled during suspend-resume cycle.

CVE-2024-49961 – media: i2c: ar0521: Use cansleep version of gpiod_set_value()

In the Linux kernel, the following vulnerability has been resolved: media: i2c: ar0521: Use cansleep version of gpiod_set_value() If we use GPIO reset from I2C port expander, we must use *_cansleep() variant of GPIO functions. This was not done in ar0521_power_on()/ar0521_power_off() functions.
