CVE-2024-50258

CVE-2024-50258 affects the Linux kernel net stack. A small gso_max_size/gso_ipv4_max_size can cause an underflow in sk_dst_gso_max_size(), making sk->sk_gso_max_size exceed device limits and trigger a BUG_ON crash during tcp_write_xmit/tso processing. The root cause is in computing tso_segs (D...

CVE-2024-50251 netfilter: nft_payload: sanitize offset and length before calling skb_checksum()

The vulnerability of the BUG_ON() function of the userfaultfd component in the Linux operating system allows a hacker to trigger a service failure.

The vulnerability of the BUGON function of the userfaultfd component in the Linux operating system is related to improper locking mechanisms. Exploiting this vulnerability can allow an attacker to cause a service failure...

kernel: scsi: qedf: Make qedf_execute_tmf() non-preemptible

A vulnerability was found in the Linux kernel's qedf driver function qedfexecutetmf, where the function call smpprocessorid is done from preemptible code before acquiring a lock which can result in BUGON when running an RT kernel. This can result in system inconsistencies...

In the Linux kernel, the following vulnerability has been resolved: md/raid5: avoid BUGON while continue reshape after reassembling Currently, mdadm support --revert-reshape to abort the reshape while reassembling, as the test 07revert-grow. However, following BUGON can be triggerred by the test:...

CVE-2022-48897

In the Linux kernel, the following vulnerability has been resolved: arm64/mm: fix incorrect filemapcount for invalid pmd The page table check trigger BUGON unexpectedly when split hugepage: ------------ cut here ------------ kernel BUG at mm/pagetablecheck.c:119! Internal error: Oops - BUG:...

CVE-2022-48897

CVE-2022-48897 affects the Linux kernel arm64 memory management, specifically a bug where pmd_leaf could be considered valid even when the PMD is invalid due to pmd_present_invalid. This caused file_map_count to be decremented and then incremented in multiple code paths, ultimately triggering a B...
