drm: Fix use-after-free read in drm_getunique()
CVE: CVE-2021-47280
Component: kernel
CWE: CWE-416
Severity: Moderate
CVSS v3: 5.6/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Release date: 2021-01-01T00:00:00+00:00

A vulnerability was found in the Linux kernel's DRM, where the drm_getunique() function can read a pointer after it has been freed. This occurs because the function retrieves a pointer without properly locking the device's master mutex, leading to a potential crash if another process modifies the pointer first.

Statement: This vulnerability is rated as a moderate severity because the risk of crash and instability in the system requires specific conditions related to concurrent access to the device's resources.

Remediation:
Red Hat has investigated whether a possible mitigation exists for this issue, and has not been able to identify a practical example. Please update the affected package as soon as possible.

NULL pointer dereference in numpy.sort in in the PyArray_DescrNew() due to missing return-value validation
CVE: CVE-2021-41495
Component: numpy
CWE: CWE-476
Severity: Moderate
CVSS v3: 7.5/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Release date: 2021-05-19T00:00:00+00:00

Null Pointer Dereference vulnerability exists in numpy.sort in NumPy &lt and 1.19 in the PyArray_DescrNew function due to missing return-value validation, which allows attackers to conduct DoS attacks by repetitively creating sort arrays. NOTE: While correct that validation is missing, an error can only occur due to an exhaustion of memory. If the user can exhaust memory, they are already privileged. Further, it should be practically impossible to construct an attack which can target the memory exhaustion to occur at exactly this place


Remediation:
heap-based buffer over-read
CVE: CVE-2021-45985
Component: lua
CWE: CWE-126
Severity: Moderate
CVSS v3: 7.5/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Release date: 2021-01-01T00:00:00+00:00

A heap-based buffer overflow issue was found in Lua Interpreter. The vulnerability can be exploited when an erroneous finalizer calls during a tail call with an invalid stack, triggering an out-of-bounds read, leading to a crash or a denial of service.

Statement: The bug exists in Lua Interpreter since v5.4.3 and fixed in v5.4.4.

RHEL-6, 7, 8 ships Lua-v5.3.4 and prior versions, which does not contains the vulnerable function. And RHEL-9 already ships Lua-v5.4.4 and above, which contains the fix. Hence, none of the Lua versions shipped with Red Hat Enterprise Linux are affected.

xen-netback: take a reference to the RX task thread
CVE: CVE-2021-47111
Component: kernel
CWE: CWE-416
Severity: Low
CVSS v3: 5.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H
Release date: 2021-01-01T00:00:00+00:00

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

xen-netback: take a reference to the RX task thread

Do this in order to prevent the task from being freed if the thread
returns (which can be triggered by the frontend) before the call to
kthread_stop done as part of the backend tear down. Not taking the
reference will lead to a use-after-free in that scenario. Such
reference was taken before but dropped as part of the rework done in
2ac061ce97f4.

Reintroduce the reference taking and add a comment this time
explaining why it's needed.

This is XSA-374 / CVE-2021-28691.

net/mlx4_en: Fix an use-after-free bug in mlx4_en_try_alloc_resources()
CVE: CVE-2021-47541
Component: kernel
CWE: CWE-416
Severity: Low
CVSS v3: 5.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H
Release date: 2021-01-01T00:00:00+00:00

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

net/mlx4_en: Fix an use-after-free bug in mlx4_en_try_alloc_resources()

In mlx4_en_try_alloc_resources(), mlx4_en_copy_priv() is called and
tmp->tx_cq will be freed on the error path of mlx4_en_copy_priv().
After that mlx4_en_alloc_resources() is called and there is a dereference
of &tmp->tx_cq[t][i] in mlx4_en_alloc_resources(), which could lead to
a use after free problem on failure of mlx4_en_copy_priv().

Fix this bug by adding a check of mlx4_en_copy_priv()

This bug was found by a static analyzer. The analysis employs
differential checking to identify inconsistent security operations
(e.g., checks or kfrees) between two code paths and confirms that the
inconsistent operations are not recovered in the current function or
the callers, so they constitute bugs.

Note that, as a bug found by static analysis, it can be a false
positive or hard to trigger. Multiple researchers have cross-reviewed
the bug.

Builds with CONFIG_MLX4_EN=m show no new warnings,
and our static analyzer no longer warns about this code.

Statement: Fixed in 8.6. Actual before 8.6. Already fixed for all versions of the Red Hat Enterprise Linux 9.
