    video: fbdev: s3fb: Check the size of screen before memset_io()

    In the Linux kernel, the following vulnerability has been resolved: video: fbdev: s3fb: Check the size of screen before memset_io() In the function s3fb_set_par(), the value of 'screen_size' is calculated by the user input. If the user provides the improper value, the value of 'screen_size' may larger than 'info->screen_size', which may cause the following bug: [ 54.083733] BUG: unable to handle page fault for address: ffffc90003000000 [ 54.083742] #PF: supervisor write access in kernel mode [ 54.083744] #PF: error_code(0x0002) - not-present page [ 54.083760] RIP: 0010:memset_orig+0x33/0xb0 [ 54.083782] Call Trace: [ 54.083788]

    spmi: trace: fix stack-out-of-bound access in SPMI tracing functions

    In the Linux kernel, the following vulnerability has been resolved: spmi: trace: fix stack-out-of-bound access in SPMI tracing functions trace_spmi_write_begin() and trace_spmi_read_end() both call memcpy() with a length of "len + 1". This leads to one extra byte being read beyond the end of the specified buffer. Fix this out-of-bound memory access by using a length of "len" instead. Here is a KASAN log showing the issue: BUG: KASAN: stack-out-of-bounds in trace_event_raw_event_spmi_read_end+0x1d0/0x234 Read of size 2 at addr ffffffc0265b7540 by task [email protected]/1314 ...

    firmware: arm_scpi: Ensure scpi_info is not assigned if the probe fails

    In the Linux kernel, the following vulnerability has been resolved: firmware: arm_scpi: Ensure scpi_info is not assigned if the probe fails When scpi probe fails, at any point, we need to ensure that the scpi_info is not set and will remain NULL until the probe succeeds. If it is not taken care, then it could result use-after-free as the value is exported via get_scpi_ops() and could refer to a memory allocated via devm_kzalloc() but freed when the probe fails.

    dm raid: fix address sanitizer warning in raid_resume

    In the Linux kernel, the following vulnerability has been resolved: dm raid: fix address sanitizer warning in raid_resume There is a KASAN warning in raid_resume when running the lvm test lvconvert-raid.sh. The reason for the warning is that mddev->raid_disks is greater than rs->raid_disks, so the loop touches one entry beyond the allocated length.

    apparmor: fix reference count leak in aa_pivotroot()

    In the Linux kernel, the following vulnerability has been resolved: apparmor: fix reference count leak in aa_pivotroot() The aa_pivotroot() function has a reference counting bug in a specific path. When aa_replace_current_label() returns on success, the function forgets to decrement the reference count of “target”, which is increased earlier by build_pivotroot(), causing a reference leak. Fix it by decreasing the refcount of “target” in that path.
