| In the Linux kernel, the following vulnerability has been resolved:
perf/amlogic: Replace smp_processor_id() with raw_smp_processor_id() in meson_ddr_pmu_create()
The Amlogic DDR PMU driver meson_ddr_pmu_create() function incorrectly uses
smp_processor_id(), which assumes disabled preemption. This leads to kernel
warnings during module loading because meson_ddr_pmu_create() can be called
in a preemptible context.
Following kernel warning and stack trace:

Changes replaces smp_processor_id() with raw_smp_processor_id() to
ensure safe CPU ID retrieval in preemptible contexts. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Check dce_hwseq before dereferencing it
[WHAT]
hws was checked for null earlier in dce110_blank_stream, indicating hws
can be null, and should be checked whenever it is used.
(cherry picked from commit 79db43611ff61280b6de58ce1305e0b2ecf675ad) |
| The rtsol(8) and rtsold(8) programs do not validate the domain search list options provided in router advertisement messages; the option body is passed to resolvconf(8) unmodified.
resolvconf(8) is a shell script which does not validate its input. A lack of quoting meant that shell commands pass as input to resolvconf(8) may be executed. |
| In some cases, the `tcp-setmss` handler may free the packet data and throw an error without halting the rule processing engine. A subsequent rule can then allow the traffic after the packet data is gone, resulting in a NULL pointer dereference.
Maliciously crafted packets sent from a remote host may result in a Denial of Service (DoS) if the `tcp-setmss` directive is used and a subsequent rule would allow the traffic to pass. |
| By default, jailed processes cannot mount filesystems, including nullfs(4). However, the allow.mount.nullfs option enables mounting nullfs filesystems, subject to privilege checks.
If a privileged user within a jail is able to nullfs-mount directories, a limitation of the kernel's path lookup logic allows that user to escape the jail's chroot, yielding access to the full filesystem of the host or parent jail.
In a jail configured to allow nullfs(4) mounts from within the jail, the jailed root user can escape the jail's filesystem root. |
| If two sibling jails are restricted to separate filesystem trees, which is to say that neither of the two jail root directories is an ancestor of the other, jailed processes may nonetheless be able to access a shared directory via a nullfs mount, if the administrator has configured one.
In this case, cooperating processes in the two jails may establish a connection using a unix domain socket and exchange directory descriptors with each other.
When performing a filesystem name lookup, at each step of the lookup, the kernel checks whether the lookup would descend below the jail root of the current process. If the jail root directory is not encountered, the lookup continues.
In a configuration where processes in two different jails are able to exchange file descriptors using a unix domain socket, it is possible for a jailed process to receive a directory for a descriptor that is below that process' jail root. This enables full filesystem access for a jailed process, breaking the chroot.
Note that the system administrator is still responsible for ensuring that an unprivileged user on the jail host is not able to pass directory descriptors to a jailed process, even in a patched kernel. |

| GStreamer is a library for constructing graphs of media-handling components. A null pointer dereference vulnerability has been discovered in the gst_matroska_demux_parse_blockgroup_or_simpleblock function within matroska-demux.c. This function does not properly check the validity of the GstBuffer *sub pointer before performing dereferences. As a result, null pointer dereferences may occur. This vulnerability is fixed in 1.24.10. |
| GStreamer is a library for constructing graphs of media-handling components. A null pointer dereference vulnerability has been discovered in the gst_matroska_demux_add_wvpk_header function within matroska-demux.c. This function does not properly check the validity of the stream->codec_priv pointer in the following code. If stream->codec_priv is NULL, the call to GST_READ_UINT16_LE will attempt to dereference a null pointer, leading to a crash of the application. This vulnerability is fixed in 1.24.10. |
| GStreamer is a library for constructing graphs of media-handling components. A null pointer dereference vulnerability has been discovered in the gst_matroska_demux_update_tracks function within matroska-demux.c. The vulnerability occurs when the gst_caps_is_equal function is called with invalid caps values. If this happen, then in the function gst_buffer_get_size the call to GST_BUFFER_MEM_PTR can return a null pointer. Attempting to dereference the size field of this null pointer results in a null pointer dereference. This vulnerability is fixed in 1.24.10. |
| GStreamer MXF File Parsing Integer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GStreamer. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation.
The specific flaw exists within the parsing of MXF video files. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
. Was ZDI-CAN-21661. |
| The gst_ps_demux_parse_psm function in gst/mpegdemux/gstmpegdemux.c in gst-plugins-bad in GStreamer allows remote attackers to cause a denial of service (invalid memory read and crash) via vectors involving PSM parsing. |
| GStreamer MXF File Parsing Use-After-Free Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GStreamer. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation.
The specific flaw exists within the parsing of MXF video files. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-22299. |
| GStreamer SRT File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GStreamer. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation.
The specific flaw exists within the parsing of SRT subtitle files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-20968. |
| DOS / potential heap overwrite in mkv demuxing using bzip decompression. Integer overflow in matroskademux element in bzip decompression function which causes a segfault, or could cause a heap overwrite, depending on libc and OS. Depending on the libc used, and the underlying OS capabilities, it could be just a segfault or a heap overwrite. If the libc uses mmap for large chunks, and the OS supports mmap, then it is just a segfault (because the realloc before the integer overflow will use mremap to reduce the size of the chunk, and it will start to write to unmapped memory). However, if using a libc implementation that does not use mmap, or if the OS does not support mmap while using libc, then this could result in a heap overwrite. |
