https://notcve.org/view.php?id=CVE-2021-47216
In the Linux kernel, the following vulnerability has been resolved: scsi: advansys: Fix kernel pointer leak Pointers should be printed with %p or %px rather than cast to 'unsigned long' and printed with %lx. Change %lx to %p to print the hashed pointer. • https://git.kernel.org/stable/c/06d7d12efb5c62db9dea15141ae2b322c2719515 https://git.kernel.org/stable/c/ad19f7046c24f95c674fbea21870479b2b9f5bab https://git.kernel.org/stable/c/5612287991debe310c914600599bd59511ababfb https://git.kernel.org/stable/c/f5a0ba4a9b5e70e7b2f767636d26523f9d1ac59d https://git.kernel.org/stable/c/cc248790bfdcf879e3094fa248c85bf92cdf9dae https://git.kernel.org/stable/c/055eced3edf5b675d12189081303f6285ef26511 https://git.kernel.org/stable/c/27490ae6a85a70242d80615ca74d0362a820d6a7 https://git.kernel.org/stable/c/d4996c6eac4c81b8872043e9391563f67 •
CVSS: -EPSS: 0%CPEs: 2EXPL: 0CVE-2021-47212 – net/mlx5: Update error handler for UCTX and UMEM
https://notcve.org/view.php?id=CVE-2021-47212
In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Update error handler for UCTX and UMEM In the fast unload flow, the device state is set to internal error, which indicates that the driver started the destroy process. In this case, when a destroy command is being executed, it should return MLX5_CMD_STAT_OK. Fix MLX5_CMD_OP_DESTROY_UCTX and MLX5_CMD_OP_DESTROY_UMEM to return OK instead of EIO. This fixes a call trace in the umem release process - [ 2633.536695] Call Trace: [ 2633.537518] ib_uverbs_remove_one+0xc3/0x140 [ib_uverbs] [ 2633.538596] remove_client_context+0x8b/0xd0 [ib_core] [ 2633.539641] disable_device+0x8c/0x130 [ib_core] [ 2633.540615] __ib_unregister_device+0x35/0xa0 [ib_core] [ 2633.541640] ib_unregister_device+0x21/0x30 [ib_core] [ 2633.542663] __mlx5_ib_remove+0x38/0x90 [mlx5_ib] [ 2633.543640] auxiliary_bus_remove+0x1e/0x30 [auxiliary] [ 2633.544661] device_release_driver_internal+0x103/0x1f0 [ 2633.545679] bus_remove_device+0xf7/0x170 [ 2633.546640] device_del+0x181/0x410 [ 2633.547606] mlx5_rescan_drivers_locked.part.10+0x63/0x160 [mlx5_core] [ 2633.548777] mlx5_unregister_device+0x27/0x40 [mlx5_core] [ 2633.549841] mlx5_uninit_one+0x21/0xc0 [mlx5_core] [ 2633.550864] remove_one+0x69/0xe0 [mlx5_core] [ 2633.551819] pci_device_remove+0x3b/0xc0 [ 2633.552731] device_release_driver_internal+0x103/0x1f0 [ 2633.553746] unbind_store+0xf6/0x130 [ 2633.554657] kernfs_fop_write+0x116/0x190 [ 2633.555567] vfs_write+0xa5/0x1a0 [ 2633.556407] ksys_write+0x4f/0xb0 [ 2633.557233] do_syscall_64+0x5b/0x1a0 [ 2633.558071] entry_SYSCALL_64_after_hwframe+0x65/0xca [ 2633.559018] RIP: 0033:0x7f9977132648 [ 2633.559821] Code: 89 02 48 c7 c0 ff ff ff ff eb b3 0f 1f 80 00 00 00 00 f3 0f 1e fa 48 8d 05 55 6f 2d 00 8b 00 85 c0 75 17 b8 01 00 00 00 0f 05 <48> 3d 00 f0 ff ff 77 58 c3 0f 1f 80 00 00 00 00 41 54 49 89 d4 55 [ 2633.562332] RSP: 002b:00007fffb1a83888 EFLAGS: 00000246 ORIG_RAX: 0000000000000001 [ 2633.563472] RAX: ffffffffffffffda RBX: 000000000000000c RCX: 00007f9977132648 [ 2633.564541] RDX: 000000000000000c RSI: 000055b90546e230 RDI: 0000000000000001 [ 2633.565596] RBP: 000055b90546e230 R08: 00007f9977406860 R09: 00007f9977a54740 [ 2633.566653] R10: 0000000000000000 R11: 0000000000000246 R12: 00007f99774056e0 [ 2633.567692] R13: 000000000000000c R14: 00007f9977400880 R15: 000000000000000c [ 2633.568725] ---[ end trace 10b4fe52945e544d ]--- • https://git.kernel.org/stable/c/6a6fabbfa3e8c656ff906ae999fb6856410fa4cd https://git.kernel.org/stable/c/a51a6da375d82aed5c8f83abd13e7d060421bd48 https://git.kernel.org/stable/c/ba50cd9451f6c49cf0841c0a4a146ff6a2822699 •
