This vulnerability stemmed from the AppArmor AFINET/AFINET6 socket mediation code, where uninitialized variables might have bee...

UBUNTU-CVE-2026-47330

Ubuntu Linux 6.8, 7.17 and 7.0 contain AppArmor SAUCE patches which can, under certain circumstances, use an uninitialized variable in notification handling code. The bug can be triggered by an unprivileged local user and can result in the incorrect caching of AppArmor notification responses...

UBUNTU-CVE-2026-47333

Ubuntu Linux 6.8, 6.17 and 7.0 contain AppArmor SAUCE patches which can potentially incorrectly compute the size of an internal buffer, leading to a heap memory out-of-bounds read in notification handling code. The bug can be triggered by an unprivileged local user and can result in invalid data...

UBUNTU-CVE-2026-47334

Ubuntu Linux 6.8, 6.17 and 7.0 contain AppArmor SAUCE patches which incorrectly sleep while holding a spinlock in notification handling code. The bug can be triggered by an unprivileged local user and can result in kernel panic or deadlock...

CVE-2026-47336

Ubuntu Linux 6.8 contains SAUCE patches with a possible use of an uninitialized variable in AppArmor AFINET/AFINET6 socket mediation code. The bug can be triggered by an unprivileged local user and could result in incorrect fine-grained mediation of network sockets...

CVE-2026-47326

Ubuntu Linux 6.8, 6.17 and 7.0 contain SAUCE patches with a memory leak in the handling of big responses to AppArmor notifications. The bug can be triggered by an unprivileged local user. The memory leak could lead to resource exhaustion...

CVE-2026-47332

Ubuntu Linux 6.8, 6.17 and 7.0 contain AppArmor SAUCE patches which incorrectly validate the size of an internal structure, leading to an out-of-bounds read in notification handling code. The bug can be triggered by an unprivileged local user and can result in information disclosure from adjacent...

UBUNTU-CVE-2026-47331

Ubuntu Linux 6.8 contains AppArmor SAUCE patches which fail to acquire a lock when modifying a linked list. An unprivileged local user could trigger the race condition that can lead to a use-after-free UAF and, theoretically, arbitrary code execution...

UBUNTU-CVE-2026-47327

Ubuntu Linux 6.8, 6.17 and 7.0 contain SAUCE patches with a possible NULL pointer dereference in the handling of AppArmor notifications. The bug can be triggered by an unprivileged local user. This can lead to a kernel oops...
