Two memory leaks in the sja1105_static_config_upload() function in drivers/net/dsa/sja1105/sja1105_spi.c in the Linux kernel before 5.3.5 allow attackers to cause a denial of service (memory consumption) by triggering static_config_buf_prepare_for_upload() or sja1105_inhibit_tx() failures, aka CID-68501df92d11.

The Spectrum Scale 4.2.0.0 through 4.2.3.21 and 5.0.0.0 through 5.0.4.3 file system component is affected by a denial of service security vulnerability. An attacker can force the Spectrum Scale mmfsd/mmsdrserv daemons to unexpectedly exit, impacting the functionality of the Spectrum Scale cluster and the availability of file systems managed by Spectrum Scale. IBM X-Force ID: 179987.

IBM Spectrum Protect 7.1 and 8.1 could allow an attacker to cause a denial of service due ti improper validation of user-supplied input. IBM X-Force ID: 183613.

Leptonica before 1.80.0 allows a heap-based buffer over-read in rasteropGeneralLow, related to adaptmap_reg.c and adaptmap.c.

An issue was discovered in the Linux kernel before 4.20.15. The nfc_llcp_build_tlv function in net/nfc/llcp_commands.c may return NULL. If the caller does not check for this, it will trigger a NULL pointer dereference. This will cause denial of service. This affects nfc_llcp_build_gb in net/nfc/llcp_core.c.

Jonathan Looney discovered that the TCP retransmission queue implementation in tcp_fragment in the Linux kernel could be fragmented when handling certain TCP Selective Acknowledgment (SACK) sequences. A remote attacker could use this to cause a denial of service. This has been fixed in stable kernel releases 4.4.182, 4.9.182, 4.14.127, 4.19.52, 5.1.11, and is fixed in commit f070ef2ac66716357066b683fb0baf55f8191a2e.

Jonathan Looney discovered that the Linux kernel default MSS is hard-coded to 48 bytes. This allows a remote peer to fragment TCP resend queues significantly more than if a larger MSS were enforced. A remote attacker could use this to cause a denial of service. This has been fixed in stable kernel releases 4.4.182, 4.9.182, 4.14.127, 4.19.52, 5.1.11, and is fixed in commits 967c05aee439e6e5d7d805e195b3a20ef5c433d6 and 5f3e2bf008c2221478101ee72f5cb4654b9fc363.

IBM Elastic Storage System 6.0.0 through 6.0.1.2 and IBM Elastic Storage Server 5.3.0 through 5.3.6.2 could allow a remote attacker to cause a denial of service by sending malformed UDP requests. IBM X-Force ID: 193486.

IBM DB2 for Linux, UNIX and Windows (includes DB2 Connect Server) 9.7, 10.1, 10.5, 11.1, and 11.5 could allow an unauthenticated attacker to cause a denial of service due a hang in the SSL handshake response. IBM X-Force ID: 193660.

The (1) udp_recvmsg and (2) udpv6_recvmsg functions in the Linux kernel before 4.0.6 provide inappropriate -EAGAIN return values, which allows remote attackers to cause a denial of service (EPOLLET epoll application read outage) via an incorrect checksum in a UDP packet, a different vulnerability than CVE-2015-5364.

On multiple SR-IOV cars it is possible for VF's assigned to guests to send ethernet flow control pause frames via the PF. This includes Linux kernel ixgbe driver before commit f079fa005aae08ee0e1bc32699874ff4f02e11c1, the Linux Kernel i40e/i40evf driver before e7358f54a3954df16d4f87e3cad35063f1c17de5 and the DPDK before commit 3f12b9f23b6499ff66ec8b0de941fb469297e5d0, additionally Multiple vendor NIC firmware is affected.

IBM MQ 9.2 CD and LTS are vulnerable to a denial of service attack caused by an error processing connecting applications. IBM X-Force ID: 190833.

Leptonica before 1.80.0 allows a heap-based buffer over-read in findNextBorderPixel in ccbord.c.

Leptonica before 1.80.0 allows a heap-based buffer over-read in pixFewColorsOctcubeQuantMixed in colorquant1.c.

TCP firewalls could be circumvented by sending a SYN Packets with other flags (like e.g. RST flag) set, which was not correctly discarded by the Linux TCP stack after firewalling.

In nDPI through 3.2, the Oracle protocol dissector has a heap-based buffer over-read in ndpi_search_oracle in lib/protocols/oracle.c.
