https://notcve.org/view.php?id=CVE-2024-46841
In the Linux kernel, the following vulnerability has been resolved: btrfs: don't BUG_ON on ENOMEM from btrfs_lookup_extent_info() in walk_down_proc() We handle errors here properly, ENOMEM isn't fatal, return the error. • https://git.kernel.org/stable/c/704c359b4093a2af650a20eaa030c435d7c30f91 https://git.kernel.org/stable/c/a580fb2c3479d993556e1c31b237c9e5be4944a3 •
CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-46840 – btrfs: clean up our handling of refs == 0 in snapshot delete
https://notcve.org/view.php?id=CVE-2024-46840
In the Linux kernel, the following vulnerability has been resolved: btrfs: clean up our handling of refs == 0 in snapshot delete In reada we BUG_ON(refs == 0), which could be unkind since we aren't holding a lock on the extent leaf and thus could get a transient incorrect answer. In walk_down_proc we also BUG_ON(refs == 0), which could happen if we have extent tree corruption. Change that to return -EUCLEAN. In do_walk_down() we catch this case and handle it correctly, however we return -EIO, which -EUCLEAN is a more appropriate error code. Finally in walk_up_proc we have the same BUG_ON(refs == 0), so convert that to proper error handling. Also adjust the error message so we can actually do something with the information. • https://git.kernel.org/stable/c/c847b28a799733b04574060ab9d00f215970627d https://git.kernel.org/stable/c/71291aa7246645ef622621934d2067400380645e https://git.kernel.org/stable/c/c60676b81fab456b672796830f6d8057058f029c https://git.kernel.org/stable/c/728d4d045b628e006b48a448f3326a7194c88d32 https://git.kernel.org/stable/c/9cc887ac24b7a0598f4042ae9af6b9a33072f75b https://git.kernel.org/stable/c/7d1df13bf078ffebfedd361d714ff6cee1ff01b9 https://git.kernel.org/stable/c/03804641ec2d0da4fa088ad21c88e703d151ce16 https://git.kernel.org/stable/c/b8ccef048354074a548f108e51d0557d6 •

https://notcve.org/view.php?id=CVE-2024-46838
In the Linux kernel, the following vulnerability has been resolved: userfaultfd: don't BUG_ON() if khugepaged yanks our page table Since khugepaged was changed to allow retracting page tables in file mappings without holding the mmap lock, these BUG_ON()s are wrong - get rid of them. We could also remove the preceding "if (unlikely(...))" block, but then we could reach pte_offset_map_lock() with transhuge pages not just for file mappings but also for anonymous mappings - which would probably be fine but I think is not necessarily expected. • https://git.kernel.org/stable/c/1d65b771bc08cd054cf6d3766a72e113dc46d62f https://git.kernel.org/stable/c/4a594acc12d5954cdc71d4450a386748bf3d136a https://git.kernel.org/stable/c/db978287e908d48b209e374b00d847b2d785e0a9 https://git.kernel.org/stable/c/4828d207dc5161dc7ddf9a4f6dcfd80c7dd7d20a •
