CVE-2025-23161

CVE-2025-23161 : In the Linux kernel, the PCI vmd driver fixed a lock context issue by changing vmd_dev::cfg_lock from spinlock_t to raw_spinlock_t so it can be used with interrupts disabled in PREEMPT_RT contexts. This avoids a sleeping-lock scenario when accessing PCI config space via pci_ops r...

glibc: buffer overflow in the GNU C Library's assert()

A flaw was found in the GNU C Library glibc. A buffer overflow condition via the assert function may be triggered due to glibc not allocating enough space for the assertion failure message string and size information. In certain conditions, a local attacker can exploit this, potentially leading t...
