"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ncdrom: rearrange last_media_change check to avoid unintentional overflow\n\nWhen running syzkaller with the newly reintroduced signed integer wrap\nsanitizer we encounter this splat:\n\n[ 366.015950] UBSAN: signed-integer-overflow in ../drivers/cdrom/cdrom.c:2361:33\n[ 366.021089] -9223372036854775808 - 346321 cannot be represented in type '__s64' (aka 'long long')\n[ 366.025894] program syz-executor.4 is using a deprecated SCSI ioctl, please convert it to SG_IO\n[ 366.027502] CPU: 5 PID: 28472 Comm: syz-executor.7 Not tainted 6.8.0-rc2-00035-gb3ef86b5a957 #1\n[ 366.027512] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.3-debian-1.16.3-2 04/01/2014\n[ 366.027518] Call Trace:\n[ 366.027523] <TASK>\n[ 366.027533] dump_stack_lvl+0x93/0xd0\n[ 366.027899] handle_overflow+0x171/0x1b0\n[ 366.038787] ata1.00: invalid multi_count 32 ignored\n[ 366.043924] cdrom_ioctl+0x2c3f/0x2d10\n[ 366.063932] ? __pm_runtime_resume+0xe6/0x130\n[ 366.071923] sr_block_ioctl+0x15d/0x1d0\n[ 366.074624] ? __pfx_sr_block_ioctl+0x10/0x10\n[ 366.077642] blkdev_ioctl+0x419/0x500\n[ 366.080231] ? __pfx_blkdev_ioctl+0x10/0x10\n...\n\nHistorically, the signed integer overflow sanitizer did not work in the\nkernel due to its interaction with `-fwrapv` but this has since been\nchanged [1] in the newest version of Clang. It was re-enabled in the\nkernel with Commit 557f8c582a9ba8ab (\"ubsan: Reintroduce signed overflow\nsanitizer\").\n\nLet's rearrange the check to not perform any arithmetic, thus not\ntripping the sanitizer."
