发布于3月6日3月6日 Members Ubuntu: (CVE-2023-52787): linux-nvidia-6.5 vulnerability Severity 4 CVSS (AV:L/AC:M/Au:N/C:P/I:P/A:P) Published 05/21/2024 Created 11/21/2024 Added 11/19/2024 Modified 11/19/2024 Description In the Linux kernel, the following vulnerability has been resolved: blk-mq: make sure active queue usage is held for bio_integrity_prep() blk_integrity_unregister() can come if queue usage counter isn't held for one bio with integrity prepared, so this request may be completed with calling profile->complete_fn, then kernel panic. Another constraint is that bio_integrity_prep() needs to be called before bio merge. Fix the issue by: - call bio_integrity_prep() with one queue usage counter grabbed reliably - call bio_integrity_prep() before bio merge Solution(s) ubuntu-upgrade-linux-nvidia-6-5 References https://attackerkb.com/topics/cve-2023-52787 CVE - 2023-52787 https://git.kernel.org/linus/b0077e269f6c152e807fdac90b58caf012cdbaab https://git.kernel.org/stable/c/b0077e269f6c152e807fdac90b58caf012cdbaab https://git.kernel.org/stable/c/b5c8e0ff76d10f6bf70a7237678f27c20cf59bc9 https://git.kernel.org/stable/c/b80056bd75a16e4550873ecefe12bc8fd190b1cf https://git.kernel.org/stable/c/e9c309ded295b7f8849097d71ae231456ca79f78 https://www.cve.org/CVERecord?id=CVE-2023-52787 View more
