Message-ID: <2025011151-CVE-2024-57799-ae66@gregkh> Date: Sat, 11 Jan 2025 13:39:54 +0100 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-cve-announce@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org> Subject: CVE-2024-57799: phy: rockchip: samsung-hdptx: Set drvdata before enabling runtime PM Description =========== In the Linux kernel, the following vulnerability has been resolved: phy: rockchip: samsung-hdptx: Set drvdata before enabling runtime PM In some cases, rk_hdptx_phy_runtime_resume() may be invoked before platform_set_drvdata() is executed in ->probe(), leading to a NULL pointer dereference when using the return of dev_get_drvdata(). Ensure platform_set_drvdata() is called before devm_pm_runtime_enable(). The Linux kernel CVE team has assigned CVE-2024-57799 to this issue. Affected and fixed versions =========================== Issue introduced in 6.9 with commit 553be2830c5f33308483e8118de748a2c69fe593 and fixed in 6.12.8 with commit 7061849a4a1752a06944a819dd1f7bfd58df7383 Issue introduced in 6.9 with commit 553be2830c5f33308483e8118de748a2c69fe593 and fixed in 6.13-rc5 with commit 9d23e48654620fdccfcc74cc2cef04eaf7353d07 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-2024-57799 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/phy/rockchip/phy-rockchip-samsung-hdptx.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/7061849a4a1752a06944a819dd1f7bfd58df7383 https://git.kernel.org/stable/c/9d23e48654620fdccfcc74cc2cef04eaf7353d07
