    Changed Description In the Linux kernel, the following vulnerability has been resolved: samples/bpf: syscall_tp_user: Fix array out-of-bound access Commit 06744f24696e ("samples/bpf: Add openat2() enter/exit tracepoint to syscall_tp sample") added two more eBPF programs to support the openat2() syscall. However, it did not increase the size of the array that holds the corresponding bpf_links. This leads to an out-of-bound access on that array in the bpf_object__for_each_program loop and could corrupt other variables on the stack. On our testing QEMU, it corrupts the map1_fds array and causes the sample to fail: # ./syscall_tp prog #0: map ids 4 5 verify map:4 val: 5 map_lookup failed: Bad file descriptor Dynamically allocate the array based on the number of programs reported by libbpf to prevent similar inconsistencies in the future Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.

    Action Type Old Value New Value
    Removed Translation Title: kernel de Linux Description: En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: samples/bpf: syscall_tp_user: corrige el acceso fuera de los límites de la matriz. Commit 06744f24696e ("samples/bpf: agrega openat2() entrada/salida del punto de seguimiento a la muestra syscall_tp") agregó dos más Programas eBPF para soportar la llamada al sistema openat2(). Sin embargo, no aumentó el tamaño de la matriz que contiene los bpf_links correspondientes. Esto conduce a un acceso fuera de los límites a esa matriz en el bucle bpf_object__for_each_program y podría dañar otras variables en la pila. En nuestra prueba QEMU, corrompe la matriz map1_fds y hace que la muestra falle: # ./syscall_tp prog #0: map ids 4 5 verificar map:4 val: 5 map_lookup falló: descriptor de archivo incorrecto Asigne dinámicamente la matriz según el número de programas reportados por libbpf para evitar inconsistencias similares en el futuro
