https://notcve.org/view.php?id=CVE-2024-39470
In the Linux kernel, the following vulnerability has been resolved: eventfs: Fix a possible null pointer dereference in eventfs_find_events() In function eventfs_find_events,there is a potential null pointer that may be caused by calling update_events_attr which will perform some operations on the members of the ei struct when ei is NULL. Hence,When ei->is_freed is set,return NULL directly. • https://git.kernel.org/stable/c/628adb842bd5e1c2c598534a7a022b8235289de6 https://git.kernel.org/stable/c/8186fff7ab649085e2c60d032d9a20a85af1d87c https://git.kernel.org/stable/c/9c2ac5e0ea7899411fd900d4681890722a020735 https://git.kernel.org/stable/c/5ade5fbdbbb1f023bb70730ba4d74146c8bc7eb9 https://git.kernel.org/stable/c/7a1b2d138189375ed1dcd7d0851118230221bd1d https://git.kernel.org/stable/c/d4e9a968738bf66d3bb852dd5588d4c7afd6d7f4 •
CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-39469 – nilfs2: fix nilfs_empty_dir() misjudgment and long loop on I/O errors
https://notcve.org/view.php?id=CVE-2024-39469
In the Linux kernel, the following vulnerability has been resolved: nilfs2: fix nilfs_empty_dir() misjudgment and long loop on I/O errors The error handling in nilfs_empty_dir() when a directory folio/page read fails is incorrect, as in the old ext2 implementation, and if the folio/page cannot be read or nilfs_check_folio() fails, it will falsely determine the directory as empty and corrupt the file system. In addition, since nilfs_empty_dir() does not immediately return on a failed folio/page read, but continues to loop, this can cause a long loop with I/O if i_size of the directory's inode is also corrupted, causing the log writer thread to wait and hang, as reported by syzbot. Fix these issues by making nilfs_empty_dir() immediately return a false value (0) if it fails to get a directory folio/page. • https://git.kernel.org/stable/c/2ba466d74ed74f073257f86e61519cb8f8f46184 https://git.kernel.org/stable/c/2ac8a2fe22bdde9eecce2a42cf5cab79333fb428 https://git.kernel.org/stable/c/405b71f1251e5ae865f53bd27c45114e6c83bee3 https://git.kernel.org/stable/c/c77ad608df6c091fe64ecb91f41ef7cb465587f1 https://git.kernel.org/stable/c/11a2edb70356a2202dcb7c9c189c8356ab4752cd https://git.kernel.org/stable/c/129dcd3e7d036218db3f59c82d82004b9539ed82 https://git.kernel.org/stable/c/d18b05eda7fa77f02114f15b02c009f28ee42346 https://git.kernel.org/stable/c/59f14875a96ef93f05b82ad3c980605f2 •
