drm/i915/bios: fix a memory leak in generate_lfp_data_ptrs
CVE: CVE-2022-50287
Component: kernel
CWE: CWE-772
Severity: Low
CVSS v3: 5.6/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Release date: 2022-01-01T00:00:00+00:00

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

drm/i915/bios: fix a memory leak in generate_lfp_data_ptrs

When (size != 0 || ptrs->lvds_ entries != 3), the program tries to
free() the ptrs. However, the ptrs is not created by calling kzmalloc(),
but is obtained by pointer offset operation.
This may lead to memory leaks or undefined behavior.

Fix this by replacing the arguments of kfree() with ptrs_block.

excessive memory consumption in _bfd_dwarf2_find_nearest_line_with_alt() in dwarf2.c
CVE: CVE-2022-48064

Release date: 2022-12-20T00:00:00+00:00

An excessive memory consumption vulnerability was identified in GNU Binutils, specifically in the function bfd_dwarf2_find_nearest_line_with_alt at dwarf2.c. An attacker could exploit this by providing a crafted ELF file, potentially leading to a denial of service attack through excessive memory usage.

memory leaks in function cmdopts_parse
CVE: CVE-2022-2963
Component: jasper
CWE: CWE-401
Severity: Moderate
CVSS v3: 7.5/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Release date: 2022-07-20T00:00:00+00:00

A vulnerability found in jasper. A memory leak bug occurs in the cmdopts_parse function, possibly causing a crash or segmentation fault.

Statement: Red Hat has determined this vulnerability to be of moderate impact as the memory leak occurs when cmdline parsing fails and causes the process to terminate right away without releasing the memory, leading to the leak. It would take repeated invocations to exhaust system memory and potentially cause service degradation over time.

tick/nohz: unexport __init-annotated tick_nohz_full_setup()
CVE: CVE-2022-49675
Component: kernel
Severity: Moderate
CVSS v3: 5.6/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Release date: 2022-01-01T00:00:00+00:00

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

tick/nohz: unexport __init-annotated tick_nohz_full_setup()

EXPORT_SYMBOL and __init is a bad combination because the .init.text
section is freed up after the initialization. Hence, modules cannot
use symbols annotated __init. The access to a freed symbol may end up
with kernel panic.

modpost used to detect it, but it had been broken for a decade.

Commit 28438794aba4 ("modpost: fix section mismatch check for exported
init/exit sections") fixed it so modpost started to warn it again, then
this showed up:

    MODPOST vmlinux.symvers
  WARNING: modpost: vmlinux.o(___ksymtab_gpl+tick_nohz_full_setup+0x0): Section mismatch in reference from the variable __ksymtab_tick_nohz_full_setup to the function .init.text:tick_nohz_full_setup()
  The symbol tick_nohz_full_setup is exported and annotated __init
  Fix this by removing the __init annotation of tick_nohz_full_setup or drop the export.

Drop the export because tick_nohz_full_setup() is only called from the
built-in code in kernel/sched/isolation.c.

drm/nouveau: fix a use-after-free in nouveau_gem_prime_import_sg_table()
CVE: CVE-2022-50454
Component: kernel
Severity: None
Release date: 2022-01-01T00:00:00+00:00

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

drm/nouveau: fix a use-after-free in nouveau_gem_prime_import_sg_table()

nouveau_bo_init() is backed by ttm_bo_init() and ferries its return code
back to the caller. On failures, ttm will call nouveau_bo_del_ttm() and
free the memory.Thus, when nouveau_bo_init() returns an error, the gem
object has already been released. Then the call to nouveau_bo_ref() will
use the freed "nvbo->bo" and lead to a use-after-free bug.

We should delete the call to nouveau_bo_ref() to avoid the use-after-free.

Statement: The change fixes undefined behaviour from shifting a signed 32-bit value by a high bit position (UBSAN: shift-out-of-bounds) by switching the literal to an unsigned type.
In practice this triggered UBSAN warnings and can crash under some configurations during framebuffer/font selection (module init / fbcon startup).
Reproducing requires loading the affected code path (e.g. initializing the framebuffer or loading the driver that calls get_default_font).
For the CVSS the PR:H, because triggering the problematic code path requires privileged/local operations (module/driver or framebuffer initialization).

Release date: 2022-01-01T00:00:00+00:00

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

usb: f_fs: Fix use-after-free for epfile

Consider a case where ffs_func_eps_disable is called from
ffs_func_disable as part of composition switch and at the
same time ffs_epfile_release get called from userspace.
ffs_epfile_release will free up the read buffer and call
ffs_data_closed which in turn destroys ffs->epfiles and
mark it as NULL. While this was happening the driver has
already initialized the local epfile in ffs_func_eps_disable
which is now freed and waiting to acquire the spinlock. Once
spinlock is acquired the driver proceeds with the stale value
of epfile and tries to free the already freed read buffer
causing use-after-free.

Following is the illustration of the race:

      CPU1                                  CPU2

   ffs_func_eps_disable
   epfiles (local copy)
					ffs_epfile_release
					ffs_data_closed
					if (last file closed)
					ffs_data_reset
					ffs_data_clear
					ffs_epfiles_destroy
spin_lock
dereference epfiles

Fix this races by taking epfiles local copy & assigning it under
spinlock and if epfiles(local) is null then update it in ffs->epfiles
then finally destroy it.
Extending the scope further from the race, protecting the ep related
structures, and concurrent accesses.

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

mmc: sdhci-of-esdhc: Fix refcount leak in esdhc_signal_voltage_switch

of_find_matching_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.
of_node_put() checks null pointer.
