CVE-2023-52560

The Linux Kernel, the operating system core itself.

Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

ALSA: hda: intel-sdw-acpi: harden detection of controller

The existing code currently sets a pointer to an ACPI handle before checking that it's actually a SoundWire controller. This can lead to issues where the graph walk continues and eventually fails, but the pointer was set already.

This patch changes the logic so that the information provided to the caller is set when a controller is found.(CVE-2021-46926)

In the Linux kernel, the following vulnerability has been resolved:

uio_hv_generic: Fix another memory leak in error handling paths

Memory allocated by 'vmbus_alloc_ring()' at the beginning of the probe function is never freed in the error handling path.

Add the missing 'vmbus_free_ring()' call.

Note that it is already freed in the .remove function.(CVE-2021-47070)

In the Linux kernel, the following vulnerability has been resolved:

asix: fix uninit-value in asix_mdio_read()

asix_read_cmd() may read less than sizeof(smsr) bytes and in this case smsr will be uninitialized.

In the Linux kernel, the following vulnerability has been resolved:

EDAC/thunderx: Fix possible out-of-bounds string access

Enabling -Wstringop-overflow globally exposes a warning for a common bug in the usage of strncat():

drivers/edac/thunderx_edac.c: In function 'thunderx_ocx_com_threaded_isr': drivers/edac/thunderx_edac.c:1136:17: error: 'strncat' specified bound 1024 equals destination size [-Werror=stringop-overflow=] 1136 | strncat(msg, other, OCX_MESSAGE_SIZE); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ... 1145 | strncat(msg, other, OCX_MESSAGE_SIZE); ... 1150 | strncat(msg, other, OCX_MESSAGE_SIZE);

...

Apparently the author of this driver expected strncat() to behave the way that strlcat() does, which uses the size of the destination buffer as its third argument rather than the length of the source buffer. The result is that there is no check on the size of the allocated buffer.

Change it to strlcat().

In the Linux kernel, the following vulnerability has been resolved:

Input: powermate - fix use-after-free in powermate_config_complete

syzbot has found a use-after-free bug [1] in the powermate driver. This happens when the device is disconnected, which leads to a memory free from the powermate_device struct. When an asynchronous control message completes after the kfree and its callback is invoked, the lock does not exist anymore and hence the bug.

Use usb_kill_urb() on pm->config to cancel any in-progress requests upon device disconnection.

In the Linux kernel, the following vulnerability has been resolved: mm/damon/vaddr-test: fix memory leak in damon_do_test_apply_three_regions() When CONFIG_DAMON_VADDR_KUNIT_TEST=y and making CONFIG_DEBUG_KMEMLEAK=y and CONFIG_DEBUG_KMEMLEAK_AUTO_SCAN=y, the below memory leak is detected. Since commit 9f86d624292c ("mm/damon/vaddr-test: remove unnecessary variables"), the damon_destroy_ctx() is removed, but still call damon_new_target() and damon_new_region(), the damon_region which is allocated by kmem_cache_alloc() in damon_new_region() and the damon_target which is allocated by kmalloc in damon_new_target() are not freed. And the damon_region which is allocated in damon_new_region() in damon_set_regions() is also not freed. So use damon_destroy_target to free all the damon_regions and damon_target. unreferenced object 0xffff888107c9a940 (size 64): comm "kunit_try_catch", pid 1069, jiffies 4294670592 (age 732.761s) hex dump (first 32 bytes): 00 00 00 00 00 00 00 00 06 00 00 00 6b 6b 6b 6b ............kkkk 60 c7 9c 07 81 88 ff ff f8 cb 9c 07 81 88 ff ff `............... backtrace: [<ffffffff817e0167>] kmalloc_trace+0x27/0xa0 [<ffffffff819c11cf>] damon_new_target+0x3f/0x1b0 [<ffffffff819c7d55>] damon_do_test_apply_three_regions.constprop.0+0x95/0x3e0 [<ffffffff819c82be>] damon_test_apply_three_regions1+0x21e/0x260 [<ffffffff829fce6a>] kunit_generic_run_threadfn_adapter+0x4a/0x90 [<ffffffff81237cf6>] kthread+0x2b6/0x380 [<ffffffff81097add>] ret_from_fork+0x2d/0x70 [<ffffffff81003791>] ret_from_fork_asm+0x11/0x20 unreferenced object 0xffff8881079cc740 (size 56): comm "kunit_try_catch", pid 1069, jiffies 4294670592 (age 732.761s) hex dump (first 32 bytes): 05 00 00 00 00 00 00 00 14 00 00 00 00 00 00 00 ................ 6b 6b 6b 6b 6b 6b 6b 6b 00 00 00 00 6b 6b 6b 6b kkkkkkkk....kkkk backtrace: [<ffffffff819bc492>] damon_new_region+0x22/0x1c0 [<ffffffff819c7d91>] damon_do_test_apply_three_regions.constprop.0+0xd1/0x3e0 [<ffffffff819c82be>] damon_test_apply_three_regions1+0x21e/0x260 [<ffffffff829fce6a>] kunit_generic_run_threadfn_adapter+0x4a/0x90 [<ffffffff81237cf6>] kthread+0x2b6/0x380 [<ffffffff81097add>] ret_from_fork+0x2d/0x70 [<ffffffff81003791>] ret_from_fork_asm+0x11/0x20 unreferenced object 0xffff888107c9ac40 (size 64): comm "kunit_try_catch", pid 1071, jiffies 4294670595 (age 732.843s) hex dump (first 32 bytes): 00 00 00 00 00 00 00 00 06 00 00 00 6b 6b 6b 6b ............kkkk a0 cc 9c 07 81 88 ff ff 78 a1 76 07 81 88 ff ff ........x.v..... backtrace: [<ffffffff817e0167>] kmalloc_trace+0x27/0xa0 [<ffffffff819c11cf>] damon_new_target+0x3f/0x1b0 [<ffffffff819c7d55>] damon_do_test_apply_three_regions.constprop.0+0x95/0x3e0 [<ffffffff819c851e>] damon_test_apply_three_regions2+0x21e/0x260 [<ffffffff829fce6a>] kunit_generic_run_threadfn_adapter+0x4a/0x90 [<ffffffff81237cf6>] kthread+0x2b6/0x380 [<ffffffff81097add>] ret_from_fork+0x2d/0x70 [<ffffffff81003791>] ret_from_fork_asm+0x11/0x20 unreferenced object 0xffff8881079ccc80 (size 56): comm "kunit_try_catch", pid 1071, jiffies 4294670595 (age 732.843s) hex dump (first 32 bytes): 05 00 00 00 00 00 00 00 14 00 00 00 00 00 00 00 ................ 6b 6b 6b 6b 6b 6b 6b 6b 00 00 00 00 6b 6b 6b 6b kkkkkkkk....kkkk backtrace: [<ffffffff819bc492>] damon_new_region+0x22/0x1c0 [<ffffffff819c7d91>] damon_do_test_apply_three_regions.constprop.0+0xd1/0x3e0 [<ffffffff819c851e>] damon_test_apply_three_regions2+0x21e/0x260 [<ffffffff829fce6a>] kunit_generic_run_threadfn_adapter+0x4a/0x90 [<ffffffff81237cf6>] kthread+0x2b6/0x380 [<ffffffff81097add>] ret_from_fork+0x2d/0x70 [<ffff ---truncated---

In the Linux kernel, the following vulnerability has been resolved:

mm/damon/vaddr-test: fix memory leak in damon_do_test_apply_three_regions()

When CONFIG_DAMON_VADDR_KUNIT_TEST=y and making CONFIG_DEBUG_KMEMLEAK=y and CONFIG_DEBUG_KMEMLEAK_AUTO_SCAN=y, the below memory leak is detected.

Since commit 9f86d624292c ("mm/damon/vaddr-test: remove unnecessary variables"), the damon_destroy_ctx() is removed, but still call damon_new_target() and damon_new_region(), the damon_region which is allocated by kmem_cache_alloc() in damon_new_region() and the damon_target which is allocated by kmalloc in damon_new_target() are not freed. And the damon_region which is allocated in damon_new_region() in damon_set_regions() is also not freed.

So use damon_destroy_target to free all the damon_regions and damon_target.
