CVE-2025-38323

Summary (CVE-2025-38323): In the Linux kernel, the ATM LECS code path (net/atm/lec.c) had a potential use-after-free due to a path that could leave a dangling pointer in dev_lec[] from lecd_attach(). The patch adds a mutex (lec_mutex) to protect dev_lecp[] uses from lecd_attach(), lec_vcc_attach(...
