Message-ID: <2025050139-CVE-2025-37758-32dd@gregkh> Date: Thu, 1 May 2025 14:57:04 +0200 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-cve-announce@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...nel.org> Subject: CVE-2025-37758: ata: pata_pxa: Fix potential NULL pointer dereference in pxa_ata_probe() From: Greg Kroah-Hartman <gregkh@...nel.org> Description =========== In the Linux kernel, the following vulnerability has been resolved: ata: pata_pxa: Fix potential NULL pointer dereference in pxa_ata_probe() devm_ioremap() returns NULL on error. Currently, pxa_ata_probe() does not check for this case, which can result in a NULL pointer dereference. Add NULL check after devm_ioremap() to prevent this issue. The Linux kernel CVE team has assigned CVE-2025-37758 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/ata/pata_pxa.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/2dc53c7a0c1f57b082931facafa804a7ca32a9a6 https://git.kernel.org/stable/c/5b09bf6243b0bc0ae58bd9efdf6f0de5546f8d06 https://git.kernel.org/stable/c/ee2b0301d6bfe16b35d57947687c664ecb815775 https://git.kernel.org/stable/c/c022287f6e599422511aa227dc6da37b58d9ceac https://git.kernel.org/stable/c/2ba9e4c69207777bb0775c7c091800ecd69de144 https://git.kernel.org/stable/c/ad320e408a8c95a282ab9c05cdf0c9b95e317985
