From: Greg Kroah-Hartman <[email protected]> Description =========== In the Linux kernel, the following vulnerability has been resolved: ALSA: ice1712: check snd_ctl_new1() return value snd_ctl_new1() can return NULL when memory allocation fails. The ice1712 driver calls snd_ctl_new1() without checking the return value before dereferencing the pointer in multiple places (ice1712.c, ice1724.c, aureon.c), which can lead to NULL pointer dereferences. Add NULL checks after snd_ctl_new1() calls and return -ENOMEM if any fails. The Linux kernel CVE team has assigned CVE-2026-64480 to this issue. Affected and fixed versions =========================== Issue introduced in 6.1.34 with commit 0df0097ea2d52401c31e550389ac758c90e6a1eb and fixed in 6.1.178 with commit 57d59be545b309d4bb54ac472b15d1e67f254d95 Issue introduced in 6.4 with commit b9a4efd61b6b9f62f83752959e75a5dae20624fa and fixed in 6.6.145 with commit 69bf1dfa3215524c4ae255bb9dce0770875abbeb Issue introduced in 6.4 with commit b9a4efd61b6b9f62f83752959e75a5dae20624fa and fixed in 6.12.96 with commit d34ad480b8896d2b486e2cf29ce1790326cad205 Issue introduced in 6.4 with commit b9a4efd61b6b9f62f83752959e75a5dae20624fa and fixed in 6.18.39 with commit 71b87108ad93d433cdb20704a8dc8852304cf2c2 Issue introduced in 6.4 with commit b9a4efd61b6b9f62f83752959e75a5dae20624fa and fixed in 7.1.4 with commit 38a7cc46370a57122fb29c4bfe48a851c0c64459 Issue introduced in 6.4 with commit b9a4efd61b6b9f62f83752959e75a5dae20624fa and fixed in 7.2-rc1 with commit 2b929b91b0f3bc6de8a844370049cd99ee8e31ff Issue introduced in 6.3.8 with commit 286e17a1c3baeb1b1cd36b63ee16e8a6e63d558e 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-2026-64480 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: sound/pci/ice1712/aureon.c sound/pci/ice1712/ice1712.c sound/pci/ice1712/ice1724.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/57d59be545b309d4bb54ac472b15d1e67f254d95 https://git.kernel.org/stable/c/69bf1dfa3215524c4ae255bb9dce0770875abbeb https://git.kernel.org/stable/c/d34ad480b8896d2b486e2cf29ce1790326cad205 https://git.kernel.org/stable/c/71b87108ad93d433cdb20704a8dc8852304cf2c2 https://git.kernel.org/stable/c/38a7cc46370a57122fb29c4bfe48a851c0c64459 https://git.kernel.org/stable/c/2b929b91b0f3bc6de8a844370049cd99ee8e31ff
