Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ksmbd: A slab-out-of-bounds issue was fixed in smbstrndupfromutf16. If the -NameOffset of smb2createreq is smaller than the Buffer offset of smb2createreq, a slab-out-of-bounds read may occur from smb2open. This patch sets the...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: hfs: Fixed a buffer overflow issue in hfsbnoderead. This patch introduces the isbnodeoffsetvalid method, which checks the requested offset value. It also introduces the checkandcorrectrequestedlength method, which checks and...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: sfc: Fixed the TX channel offset when using legacy interrupts. In the legacy interrupt mode, the txchanneloffset was hardcoded to 1, but this is incorrect if efxsepparatetxChannels is set to false. In that case, the offset is 0...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Soundwire: Cadence – fix invalid PDI offset For some reason, we added an offset to the PDI; presumably to skip PDI0 and PDI1, which are reserved for BPT. However, this code is completely incorrect and leads to out-of-bounds acces...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15

In the Linux kernel, the following vulnerability has been resolved: net: nsh: Use the correct macoffset to unwind the gsoskb in nshgsosegment. As shown in the call trace, the skbpanic occurred due to an incorrect skb-macheader in nshgsoSegment. Invalid opcode: 0000 1 PREEMPT SMP KASAN PTI CPU: 3...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: ftruncate: passing a signed offset. The old ftruncate system call, which uses the 32-bit offt type, misses a sign extension when called in compat mode on 64-bit architectures. As a result, passing a negative length accidentally...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ksmbd: An out-of-bounds access issue in parsesecdesc has been fixed. If osidoffset, gsidoffset, and dacloffset can be greater than smbntsdstruct.size. If they are smaller, it could lead to an out-of-bounds situation. Additionally...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: iomap: Avoid truncating the 64-bit offset to 32 bits. On 32-bit kernels, iomapwritedelallocscan inadvertently used a 32-bit position due to folionextindex returning a unsigned long value. This could lead to an infinite loop when...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: block: Fixed an incorrect offset in biotruncate The biotruncate function clears the buffer outside of the last block of bdev. However, the current implementation of biotruncate uses the wrong offset for the page. As a result, it...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: vfio/platform: checking the bounds of read/write syscalls. The count and offset parameters are passed from user space without being checked. Only the offset parameter is capped at 40 bits, which can be used to read/write data...

Astra Linux – Vulnerability in Vim

Use of out-of-range pointer offset in the GitHub repository vim/vim before version 8.2...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Validate data run offset This adds sanity checks for the data run offset. We should ensure that the data run offset is valid before attempting to unpack the data; otherwise, we may encounter use-after-free errors or...

Astra Linux – Vulnerability in bluez

The clifeatreadcb function in src/gatt-database.c does not perform bounds checks on the 'offset' variable before using it as an index into an array for reading...

Astra Linux – Vulnerability in Vim

Use of out-of-range pointer offset in the GitHub repository vim/vim before version 8.2.4418...

Astra Linux – Vulnerability in Qemu

A bug in QEMU could cause a guest I/O operation that is normally directed to an arbitrary disk offset to be directed instead to offset 0. This could potentially overwrite the VM’s boot code. For example, this could be exploited by L2 guests who have a virtual disk vdiskL2 stored on the virtual di...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: x86/sgx: Add a overflow check in sgxvalidateoffsetlength The sgxvalidateoffsetlength function verifies the "offset" and "length" arguments provided by the user space. However, there was a lack of an overflow check when these...

Astra Linux – Vulnerability in OpenSSL

AES OCB mode for 32-bit x86 platforms, using the AES-NI assembly-optimized implementation, may not encrypt all of the data under certain circumstances. This could reveal sixteen bytes of data that were already present in the memory but were not written. In the special case of “in-place” encryptio...

Astra Linux – Vulnerability in Wireshark

In Wireshark versions 3.2.0 to 3.2.7, the GQUIC dissector could crash. This issue was addressed in the epan/dissectors/packet-gquic.c file by correcting the implementation of offset advancement...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: Squashfs: Check that the metadata block offset is within the acceptable range. Syzkaller reports a “general protection fault in squashfscopydata”. This issue is ultimately caused by a corrupted index look-up table, which resul...
