USN-6726-3: Linux kernel (Xilinx ZynqMP) vulnerabilities

Pratyush Yadav discovered that the Xen network backend implementation in the Linux kernel did not properly handle zero length data request, leading to a null pointer dereference vulnerability. An attacker in a guest VM could possibly use this to cause a denial of service host domain crash...

UBUNTU-CVE-2024-26850

In the Linux kernel, the following vulnerability has been resolved: mm/debugvmpgtable: fix BUGON with pud advanced test Architectures like powerpc add debug checks to ensure we find only devmap PUD pte entries. These debug checks are only done with CONFIGDEBUGVM. This patch marks the ptes used fo...

CVE-2024-26850

CVE-2024-26850 concerns the Linux kernel bug in mm/debug_vm_pgtable related to pud_advanced_tests for PUD entries on architectures such as powerpc. Affected code could trigger a kernel panic (BUG_ON) when debug checks are active (CONFIG_DEBUG_VM), with traces pointing to radix_pgtable.c and pgtab...

CVE-2024-26847 powerpc/rtas: use correct function name for resetting TCE tables

In the Linux kernel, the following vulnerability has been resolved: powerpc/rtas: use correct function name for resetting TCE tables The PAPR spec spells the function name as "ibm,reset-pe-dma-windows" but in practice firmware uses the singular form: "ibm,reset-pe-dma-window" in the device tree...
