[PATCH openEuler-1.0-LTS] nilfs2: fix potential out-of-bounds memory access in nilfs_find_entry()
by Zizhi Wo 02 Jan '25

From: Ryusuke Konishi <konishi.ryusuke(a)gmail.com> stable inclusion from stable-v5.4.287 commit 09d6d05579fd46e61abf6e457bb100ff11f3a9d3 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEANS CVE: CVE-2024-56619 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- commit 985ebec4ab0a28bb5910c3b1481a40fbf7f9e61d upstream. Syzbot reported that when searching for records in a directory where the inode's i_size is corrupted and has a large value, memory access outside the folio/page range may occur, or a use-after-free bug may be detected if KASAN is enabled. This is because nilfs_last_byte(), which is called by nilfs_find_entry() and others to calculate the number of valid bytes of directory data in a page from i_size and the page index, loses the upper 32 bits of the 64-bit size information due to an inappropriate type of local variable to which the i_size value is assigned. This caused a large byte offset value due to underflow in the end address calculation in the calling nilfs_find_entry(), resulting in memory access that exceeds the folio/page size. Fix this issue by changing the type of the local variable causing the bit loss from "unsigned int" to "u64". The return value of nilfs_last_byte() is also of type "unsigned int", but it is truncated so as not to exceed PAGE_SIZE and no bit loss occurs, so no change is required.

From: Paulo Alcantara <pc(a)manguebit.com> stable inclusion from stable-v6.6.64 commit 46f8e25926817272ec8d5bfbd003569bdeb9a8c8 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEAG4 CVE: CVE-2024-53185 -------------------------------- commit 4bdec0d1f658f7c98749bd2c5a486e6cfa8565d2 upstream.

Commit b0abcd65ec54 ("smb: client: fix UAF in async decryption") added a @server->cipher_type check to conditionally call smb3_crypto_aead_allocate(), but that check would always be false as @server->cipher_type is unset for SMB3.02. Fix the following KASAN splat by setting @server->cipher_type for SMB3.02 as well. mount.cifs //srv/share /mnt -o vers=3.02,seal,...
