Canonical Ubuntu Linux is a Linux operating system developed by the British company Canonical. The Canonical Ubuntu Linux 6.8 version contained a security vulnerability; this vulnerability stemmed from potential null pointer dereferencing during the processing of AppArmor notifications, which cou...

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-2026-47336

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...

UBUNTU-CVE-2026-47328

Ubuntu Linux 6.8, 6.17 and 7.0 contain AppArmor SAUCE patches which incorrectly attempt to free a pointer which was not previously kmallocd, while at the same time leaking allocated memory. The bug can be triggered by an unprivileged local user and can result in the corruption of slab metadata an...

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-2026-47335

Ubuntu Linux 6.8 contains 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 panic...

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...

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...

CVE-2026-45965

A flaw was found in the AppArmor security module of the Linux kernel. When the exportbinary parameter is disabled at runtime, a previously loaded profile that is subsequently replaced can lead to a NULL pointer dereference. This occurs when the system attempts to resolve symbolic links to raw dat...

CVE-2026-45966

A flaw was found in the AppArmor security module within the Linux kernel. This vulnerability occurs when the system processes file descriptors, which are references to open files or other I/O resources, using a specific inter-process communication mechanism called SCMRIGHTS. A missing check for...

CVE-2026-46055

A flaw was found in the AppArmor security module of the Linux kernel. A missing string termination in the aadfamatch function can lead to a string buffer overrun. This vulnerability could allow a local attacker to cause a denial of service DoS or potentially disclose sensitive information due to ...

EUVD-2026-32250

In the Linux kernel, the following vulnerability has been resolved: apparmor: fix NULL pointer dereference in unixneedsrevalidation When receiving file descriptors via SCMRIGHTS, both the socket pointer and the socket's sk pointer can be NULL during socket setup or teardown, causing NULL pointer...

EUVD-2026-32249

In the Linux kernel, the following vulnerability has been resolved: apparmor: fix invalid deref of rawdata when exportbinary is unset If the exportbinary parameter is disabled on runtime, profiles that were loaded before that will still have their rawdata stored in apparmorfs, with a symbolic lin...

EUVD-2026-32359

In the Linux kernel, the following vulnerability has been resolved: apparmor: Fix & Optimize table creation from possibly unaligned memory Source blob may come from userspace and might be unaligned. Try to optize the copying process by avoiding unaligned memory accesses. - Added Fixes tag - Added...

EUVD-2026-32350

In the Linux kernel, the following vulnerability has been resolved: apparmor: avoid per-cpu hold underflow in aagetbuffer When aagetbuffer pulls from the per-cpu list it unconditionally decrements cache-hold. If hold reaches 0 while count is still non-zero, the unsigned decrement wraps to UINTMAX...
