Message-ID: <2024073034-CVE-2024-42153-c515@gregkh> Date: Tue, 30 Jul 2024 09:48:11 +0200 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-cve-announce@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org> Subject: CVE-2024-42153: i2c: pnx: Fix potential deadlock warning from del_timer_sync() call in isr Description =========== In the Linux kernel, the following vulnerability has been resolved: i2c: pnx: Fix potential deadlock warning from del_timer_sync() call in isr When del_timer_sync() is called in an interrupt context it throws a warning because of potential deadlock. The timer is used only to exit from wait_for_completion() after a timeout so replacing the call with wait_for_completion_timeout() allows to remove the problematic timer and its related functions altogether. The Linux kernel CVE team has assigned CVE-2024-42153 to this issue. Affected and fixed versions =========================== Issue introduced in 2.6.20 with commit 41561f28e76a and fixed in 4.19.318 with commit a349e5ab4dc9 Issue introduced in 2.6.20 with commit 41561f28e76a and fixed in 5.4.280 with commit effe0500afda Issue introduced in 2.6.20 with commit 41561f28e76a and fixed in 5.10.222 with commit 2849a1b747cf Issue introduced in 2.6.20 with commit 41561f28e76a and fixed in 5.15.163 with commit 3503372d0bf7 Issue introduced in 2.6.20 with commit 41561f28e76a and fixed in 6.1.98 with commit 3d32327f5cfc Issue introduced in 2.6.20 with commit 41561f28e76a and fixed in 6.6.39 with commit 92e494a7568b Issue introduced in 2.6.20 with commit 41561f28e76a and fixed in 6.9.9 with commit 27cd3873fa76 Issue introduced in 2.6.20 with commit 41561f28e76a and fixed in 6.10 with commit f63b94be6942 Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community. Unaffected versions might change over time as fixes are backported to older supported kernel versions. The official CVE entry at https://cve.org/CVERecord/?id=CVE-2024-42153 will be updated if fixes are backported, please check that for the most up to date information about this issue. Affected files ============== The file(s) affected by this issue are: drivers/i2c/busses/i2c-pnx.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/a349e5ab4dc9954746e836cd10b407ce48f9b2f6 https://git.kernel.org/stable/c/effe0500afda017a86c94482b1e36bc37586c9af https://git.kernel.org/stable/c/2849a1b747cf37aa5b684527104d3a53f1e296d2 https://git.kernel.org/stable/c/3503372d0bf7b324ec0bd6b90606703991426176 https://git.kernel.org/stable/c/3d32327f5cfc087ee3922a3bcdcc29880dcdb50f https://git.kernel.org/stable/c/92e494a7568b60ae80d57fc0deafcaf3a4029ab3 https://git.kernel.org/stable/c/27cd3873fa76ebeb9f948baae40cb9a6d8692289 https://git.kernel.org/stable/c/f63b94be6942ba82c55343e196bd09b53227618e
