[REJECTED CVE] In the Linux kernel, the following vulnerability has been resolved: net/rds: Fix UBSAN: array-index-out-of-bounds in rds_cmsg_recv The Linux kernel CVE team has assigned CVE-2024-26613 to this issue.

Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.

In the Linux kernel, the following vulnerability has been resolved: net/rds: Fix UBSAN: array-index-out-of-bounds in rds_cmsg_recv Syzcaller UBSAN crash occurs in rds_cmsg_recv(), which reads inc->i_rx_lat_trace[j + 1] with index 4 (3 + 1), but with array size of 4 (RDS_RX_MAX_TRACES). Here 'j' is assigned from rs->rs_rx_trace[i] and in-turn from trace.rx_trace_pos[i] in rds_recv_track_latency(), with both arrays sized 3 (RDS_MSG_RX_DGRAM_TRACE_MAX). So fix the off-by-one bounds check in rds_recv_track_latency() to prevent a potential crash in rds_cmsg_recv(). Found by syzcaller: ================================================================= UBSAN: array-index-out-of-bounds in net/rds/recv.c:585:39 index 4 is out of range for type 'u64 [4]' CPU: 1 PID: 8058 Comm: syz-executor228 Not tainted 6.6.0-gd2f51b3516da #1 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.15.0-1 04/01/2014 Call Trace: <TASK> __dump_stack lib/dump_stack.c:88 [inline] dump_stack_lvl+0x136/0...
